A glitch is the unintended behavior of a game, usually a result of a programming mistake, or by overlooking a specific (usually esoteric) sequence of events that players can, but weren't expected to perform during normal gameplay. A glitch is usually detrimental to the player's experience, and can be so minor that it easily goes unnoticed. Sometimes, however, it can be severe enough to freeze the game, cause the playable character to die for no apparent reason, or even corrupt the entire save file and force the player to restart from the beginning. In certain cases though, glitches can be helpful to players. Glitching a game, however, refers to a player intentionally triggering the unintended behavior.
In the Kirby games
To achieve this glitch, the player must make Kirby jump, then rapidly press left and right on the D-pad. If done correctly, Kirby will begin to moonwalk. After about .7 seconds, he will begin to walk normally again.
Behind the Foreground
In Bubbly Clouds (Level 4) Kirby will reach a room with a Mint Leaf on a platform near a body of water. If the player has Kirby inhale the Mint Leaf while holding up on the D-pad just as Kirby touches the surface of the water, Kirby will go behind the foreground. He can still harm enemies (or be harmed by enemies), and the effect of this glitch will go away upon losing a life or entering a door.
Superspicy Kirby Underwater
In the third level (Float Islands), Kirby will come across Superspicy Curry. If he manages to inhale as he is touching water, he will be able to use the Superspicy Curry's power underwater; under normal circumstances, Kirby is supposed to lose this power-up as soon as he touches a body of water.
In Float Islands, if the player has Kirby ascend upward right after defeating Kaboola, he / she will be able to access the bottom of the screen that normally contains the stage's Sparkling Star, which contains the death tiles and thus will cause the player to lose a life.
Early Ending Credits
Firstly, Kirby must have the Stone ability for this to work. In Stage 1 of Orange Ocean, go through the first door to the Rolling Turtle fight. Use the Stone ability on the block Kirby is standing on, and he should be "splashing" up and down. Use the ability again, and bizarre things should start to happen, such as glitchy tilesets appearing. After a while (when the whole screen is covered), the credits should appear, but be careful. Doing this may result in freezing the game, crashing it, or even causing the loss of the player's save file.
(Somewhat) Infinite Microphone
During the battle with Paint Roller, Kirby has to hit him three times (so his health is halfway down), and then swallow the Microphone enemy when it appears. Then, Kirby has to use it twice to damage Paint Roller so that one Mike remains. Immediately move to the middle of the screen and use the last Mike right where the Star Rod piece would appear. The level will end before Kirby loses his ability, so the counter will be at zero, which really means 266 more uses. When Kirby uses the Mike ability, the screen will become distorted with glitchy sprites (these sprites change depending where the ability is being used), although this doesn't negatively impact the game. This glitch can be attempted both in the main game and in the sub-game VS Boss.
Shine and Bright's Speedy Sprites
Kirby must have the Hi-Jump ability. Then, make sure Mr. Bright (sun) is in the sky and Mr. Shine (moon) is on the ground standing close to Bright. When Mr. Bright uses his energy beam attack, Kirby must use Hi-Jump to go through Mr. Shine, the energy beam, and Mr. Bright unharmed. The invincibility of the jump should wear off while inside Mr. Bright, so Kirby will take damage. At that point, most of the screen will become pixelated and filled with garbled sprites (the player can still see the game clearly) and everything will move slightly faster.
To perform this glitch, Kirby has to discard the current Copy Ability he has and immediately pause the game. Then, Kirby has to leave the stage he is currently in. If performed correctly, when the player presses B, Kirby will splash water on land. If Kirby forfeits the star from this "ability" and inhales it, Kirby will start flashing as if he inhaled an ability-bearing enemy, but no ability is obtained from actually swallowing the star. The same effect can also be achieved if the player pauses the game just as Kirby loses his copy ability from being hit by an enemy.
A variation of the above glitch can be performed with either the Sword, Hammer, or Parasol abilities. Upon exiting the level after following the steps for the Water Splash glitch, Kirby will still be carrying a sword, hammer, or parasol depending which ability was used and use his normal pink palette, instead of the orange-tinted palette used for most Copy Abilities. Now, if Kirby is hit by an enemy, he will not lose his weapon. Forfeiting his "ability" and inhaling the star will also yield nothing when swallowed. Losing a life will also cause Kirby to lose his "ability".
Another variation of the Water Splash glitch allows Kirby to keep the UFO ability when hit and use his pink palette instead of his orange one. Normally, Kirby would lose the UFO ability upon completing a level, but through this glitch, he can continue to use it in any level and in the overworld (though the standard Kirby sprite will still be used as the player exits doors before going back to the UFO). The star, just as it was with the normal glitch and its other variation, causes Kirby to flash as if he can obtain an ability, but provides no ability when swallowed.
Kirby Color Change
The player must get to the top stage of Kracko Land. Once Mr. Bright is defeated, the Chuckie there will change into a Hurly, and Mr. Shine will appear. The player must then intentionally fall back into the middle stage, and launch back up into the top stage. Mr. Bright and Chuckie will be there again, like normal. However, for a split second during the transition from the middle stage to the top, Hurly will be there instead of Chuckie.
Dying in the Overworld
The player must make sure Kirby only has one remaining piece of health and is currently in a previously cleared stage. Pause immediately after Kirby takes damage. The player can then reset the game or exit the stage. If the game is reset, when the player returns to their file and selects a level to enter, Kirby will arrive on his Warp Star and die as soon as he touches the ground. If Kirby exits the stage instead, he will die after leaving the stage's door.
Delayed Animal Friend Death
A variation of the above glitch with (slightly) more favorable results. If the player follows the same steps, Kirby's current Animal Friend will die, but Kirby himself will still be alive (and thus, no lives are lost).
Obtain the Burning ability and enter Stage 4. Destroy one of the lowest ability blocks, then hit Kirby into the tiny space left. Instead of breaking the block Kirby bumps into, he will hurt the Blocky next to it. This can happen multiple times before the Blocky is defeated.
Pinball Block Rapid Score
This glitch can also be performed with the Burning ability in Stage 4, as in the above glitch. Do not break the ability blocks next to either pinball block. When Kirby is directly beneath a pinball block, press B. Kirby will rush through all the blocks in his way and through the pinball block... but then hit the ceiling. The pinball block is immediately below the ceiling, and with a wall to the left and right, Kirby will be trapped inside the pinball block, earning rapid points. He will eventually fire out the bottom.
Border Line Oversight
The game will only recognize Kirby as having cleared the border line if the player gets a score that matches or is greater than the border line bonus for each stage. This means that if a player manages to get a high enough score (ex. by gaining multiple lives, grabbing bonus items, etc.) while failing to clear the border line, the game will display the border line bonus screen anyway and save that progress. Alternatively, if a player clears the border line but manages to get a low score (ex. by having few lives, activating the border line with very few blocks left, etc.), the game will act as if Kirby hasn't cleared the border line and will skip to the high score screen instead.
This glitch can only be attempted in Milky Way Wishes. First, select the Bomb ability while Kirby is underwater. Kirby will proceed to hold a bomb over his head as he normally does, and the bomb will explode right away. However, when Kirby jumps out of water and onto the ground, he will act as if he is still holding the bomb when he's really holding nothing at all. This glitch was fixed in Kirby Super Star Ultra .
With the Wheel ability, transform into the wheel and hold down the B button until Kirby hits a wall. Let go of the B button and he should still be rolling slowly. Kirby is now invincible, and when an enemy touches him, it does quick damage.
In Revenge of Meta Knight, after Meta Knight is beaten and the screen fades to black, have Kirby turn his ability into a Helper right before the screen becomes completely black. If done correctly, in the scene where Kirby falls onto the Wheelie, the helper he just called will be glitched into the sprite of the Wheelie he is riding.
In the battle against Marx, have Kirby use an ability that can grab enemies (Jet, Suplex, Ninja, etc.). When Marx drops the orb that breaks into a wave of ice, try to grab that orb the moment it hits the ground. If done too early, Kirby grabs the orb. Too late, and he either blocks the ice wave or gets frozen. If timed just right, the orb will turn into another Marx.
To trigger the glitch, step into an elevator with the Sword ability. Move the elevator up, and perform an attack as it ascends. Kirby will slip through, and fall. This is fixed in the remake.
When fighting Kracko in Spring Breeze, hit him five times with the normal Hammer attack. Quit and then return to the same level. When the player reaches Kracko again, the player must hit him with Hammer Swing. Kracko will disappear for a few seconds and come back as a random character, or even a random object. Things he can transform into include Kracko Jr., Heavy Lobster, a purple Waddle Dee, the sword offered for the battle with Meta Knight, and an orb from Galactic Nova Nucleus.
This glitch can be performed when playing the game on a Nintendo Wii with a GameCube controller or the Wii Classic Controller Pro; simply push the D-pad left while pushing the joystick (not the C-stick). If the Classic Controller Pro is used Kirby will seem to walk backwards but remain stationary. On the GameCube controller, he will start walking backwards. Kirby trembles violently while doing the moonwalk on a console, but will move smoothly on emulators.
Cairn through Walls
Kirby must inhale a Cairn and hold it above his head. He must then walk up to a tall column or pillar and throw the Cairn. Its bottom rock will break when it hits the column, but its middle rock and head will pass through the column. This glitch can be be performed in Stage 4 of Shiver Star, among other stages.
Whispy Woods' Extra Air Puff
Right after Whispy shoots his second or fourth air puff, Kirby must hit him. He will take damage, then will act as if he's blowing an air puff, but no damaging air puff will appear. This can actually be observed in the end credits on Normal mode.
Meta Knight's Broken Health Meter
While Meta Knight is taunting Kirby with his sword and jumping off his platform, Kirby must hit Meta Knight using the Sword ability before the knight's health meter fills up completely. He will take damage, but his health meter won't appear to go down. When Kirby hits him again, Meta Knight will take damage and his health meter will go down, but there will also be a gap in it, leaving behind the first section of health that was lost. Meta Knight's meter behaves normally upon Kirby's third attack.
Walk Through the Fire Lion
The player must wait until the Fire Lion attempts to pounce on Kirby, then move Kirby away so that the attack fails, leaving the Fire Lion lying face-first on the ground. Kirby may move freely right through the immobilized Lion until he starts moving again.
Bosses' Weak Spots
Mr. Shine's rolling attack on the ground provides no damage if Kirby is crouching. Kirby can also jump through Heavy Mole's thin arms (close to the circular, red blade) while they are fully extended. Likewise, Meta Knight can't harm Kirby with aerial attacks if Kirby is floating at the very top of the screen. If Kirby stands close enough in front of King Dedede when he tries to hit Kirby with his hammer, Kirby will not take damage. Also, if Kirby is standing close enough to Dedede and crouches, he will not be inhaled. Kirby absolutely can't be harmed by Dedede in any manner (except for his floating around and his subsequent air puff) if Kirby is floating at the very top of the screen. Nightmare's whirlwind attack will not harm Kirby if he stands in his normal fashion upon ground; some of these safeties do not apply to Meta Knight (the player) in his sub-game.
Forcing an Ability Star Through a Wall
While fighting Heavy Mole, Kirby must dig a pit (or wait until Heavy Mole does it for the player) and drop his Ability Star into the pit. The player needs to ensure it cannot bounce out of the pit. When the autoscroll sandwiches the star, it will be forced to move into the wall to its right, bouncing incessantly until it self-destructs, is inhaled, or comes out of the wall.
Knights Slipping Off Edges
If a Sword or Blade Knight is on the very edge of an open-ended platform, it can fall off. The knight must be the kind that waits until Kirby comes close enough to it to slash at him. If Kirby stands out of range and fires any projectile at the knight, it will attempt to block the attack. Upon its 12th consecutive attempt, it will fall off the platform onto anything below it. This glitch also works in Kirby & the Amazing Mirror, but is activated only by a Sword Knight's slashing at Kirby by its own choice, landing at the edge of its platform. Boxin may also be seen falling off their platforms while dancing around near the edge. This phenomenon of enemies "slipping" is more difficult to observe in Kirby & the Amazing Mirror than in Kirby: Nightmare in Dream Land.
If a Blipper follows Kirby (and doesn't ram into him), after approximately 28 seconds, it will choose to permanently retreat. Kirby can then chase it in any direction he wants. This glitch can also be replicated in Kirby & the Amazing Mirror, but in that game, the retreating Blippers are more responsive to Kirby's chasing them.
For both abilities, the regular attack can be glitched by performing the attacks consecutively as quickly as possible. Only three projectiles seem to be allowed in the screen's view at once. Every additional attacks' projectile will be non-existent so long as three are currently on-screen. Kirby will only go through the motions of throwing the Cutter or swinging the Star Rod and no projectile emerges. Where the invisible projectile should be if it were visible, no damage is dealt to any enemy. The Star Rod's glitch only occurs in the final battle against Nightmare.
The player should cause Kirby to dash, then jump while holding left or right on the D-pad; then the player must let go exactly before Kirby touches the ground. Then, exactly after Kirby touches ground, the player must hold or press the same directional button pressed before. If the process is executed skillfully, Kirby will continue to dash, but without leaving any trail of dust behind him as well as no "dash" sound effect.
Kirby's Long-Fall, No-Bounce, Instant Attack
Falling from high enough in the air will cause Kirby to bounce onto the ground or most enemies upon impact. Pressing the B button will activate Kirby's simplest attacks; if the player times Kirby's attack so that it matches the very instant Kirby faceplants, the attack will be performed and Kirby will not bounce off the ground. Using the Sword ability's slow, normal slash attack provides the most distinct visual and audible feeling out of all the abilities when performing this glitch. The player will often still hear the "bounce" sound effect upon glitching. This glitch may also be performed in Kirby & the Amazing Mirror.
Flinging Enemies Through the Ground
Using Backdrop or Throw, Kirby may fling enemies downward through a platform he is on. The platform must be thin (for instance, all the cloud platforms when fighting Kracko are this thick, even the main arena platform). To perform the glitch using Backdrop, Kirby should grab the enemy in mid-air at a height of about the same thickness as the platform beneath. Backdrop is difficult to use for this glitch because the grab height required is terribly precise (likely down to a single pixel); utilizing Throw is much easier and requires virtually no precision. With the Throw ability, Kirby can grab an enemy while it is on the ground; falling; about to fall; jumping into; or flying, hovering, or floating in the air (ex. cannonballs fired from Shotzo, Bombers teetering on an edge,etc.) Kirby can then fling the enemy downward either left or right, while Kirby is standing on thin ground. If done correctly, thrown enemies should fly right through. However, there are exceptions: some stationary Sir Kibbles (in Stage 5 of Butter Building) can be thrown down through a platform, while identical others can't (unless they are grabbed while hopping over their own cutters). In the same aforementioned Level and Stage, Waddle Doos walking with their parasols can only be thrown through every alternate, separate thin platform they walk on. Only certain enemies will work for this glitch; they generally cannot be types that hop.
Invisible Wall-Bounce Impact
Using the Ball ability, Kirby must hit the side of a wall after he bounces upward off the ground. Once he reaches his highest point in the air, he will appear to be flattened, have stars around him, and be accompanied by the "impact" sound effect, similar to the results of a normal wall, ceiling, or ground impact (except Kirby won't bounce off this "invisible wall"). Kirby must be glowing blue as he falls to the ground (before bouncing up and off the wall) to activate this glitch. Thus, a tiny bounce won't work. This glitch will also not work if Kirby touches the ceiling once he has bounced off the wall, because he will not have reached his highest potential ascent in the air.
A Mouthful of Nothing
When fighting a Boss, Kirby must try to inhale an object right after he deals the final blow toward the Boss. If the item is close enough to Kirby's mouth when the Boss takes the final damage, the object will explode and disappear, but Kirby's mouth will become full with the already-destroyed object. This is best accomplished when fighting Whispy Woods in his last bit of health by inhaling an apple, shooting it at him, and being in the process of inhaling another apple when the first apple fired deals the final blow.
The Dual-Side Platform Teleport
Kirby must have the Ball ability. When bouncing at full power in ball form on the edge of a solid platform, immediately come out of ball form upon closely approaching the underside or topside. Move left or right, as the case may be, off the open edge of the platform upon reaching its surface. In normal form, Kirby will travel at top speed either upwards (to the height of his Ball form's previous bounce's terminal velocity; in other words, to his max bounce height) or downwards (until the touches ground). Changing out of ball form right after a bounce at full speed also provides Kirby a giant leap (or, in some cases, a quick descent)!
Extra Bounce While Discarding Abilities
As soon as Kirby bounces off the ground by falling, discard his ability star. This will make him bounce a second time during the first bounce.
Reset Kirby's Pose
Kirby must have an ability before performing this glitch. While stationed on a ladder, drop Kirby's current ability. Whatever posture Kirby is in when he stops climbing the ladder is automatically reset to a generic pose.
Delay in Ice Cube Disintegration
While the ice cube is still forming after using the Freeze or Ice abilities on a suitable enemy, kick it and hit another enemy with it. The cube will continue to form until it's complete, even after the enemy is destroyed by it. When complete, it will automatically disintegrate like it should have when it first hit the enemy; discarding either of these abilities while an ice cube is forming also produces a delayed disintegration.
Upon releasing an Ability Star, the player must immediately be in the process of acquiring the Spark or the Freeze abilities; pressing and holding B exactly after the mini-cutscene of Kirby's gaining either ability will temporarily allow the player to hear no sound from the newly-gained ability's attack. This glitch is also applicable to almost all of Kirby's abilities' attack sounds found in the game; for example, using Star Spit right when a previously spat-out star hits an object will produce a silent attack. Many sound effects in the game (as well as in Kirby & the Amazing Mirror) overlap and can cancel each other out. For example, when using Sword's aerial attack, the initial "float" sound effect is eliminated if Kirby is made to float immediately after the attack. This "overlap"effect can also be observed in Kirby Super Star Ultra.
Kirby's Lightning-fast Mouth
Kirby must have an ability, float into the air, and discard the ability immediately after he exhales (and subsequently creates an air puff); upon discarding the ability, Kirby will instantaneously shut his mouth, and his mouth may not even be seen open, so long as there is extremely little time between Kirby's exhaling and subsequent discarding. This glitch may also be observed in Kirby & the Amazing Mirror.
Using a single Star Spit, Kirby can allow the water to block the attack if he performs the attack the instant he enters / leaves the water's surface.
Blipper's Mid-Air Splash
Using Backdrop, Kirby can rush and grab a jumping Blipper; the instant Kirby throws the Blipper, a splash of water will be seen in the air right where the Blipper was released; a second, normal splash is still seen once these types of Blippers are thrown down into water beneath them. The Throw ability may also be used in any direction against these Blippers to perform this glitch.
When Kirby drops an Ability Star while underwater, he will automatically perform a single stroke through the water.
Recoil-Free Slide Attack
Kirby will not bounce backwards if performing a slide attack that damages a Star Block first and then an enemy right after. This glitch also exists in Kirby & the Amazing Mirror, but only applies to the situation when Kirby performs this attack into an enemy from the greatest distance possible: the single pixel of Kirby starting to stand up (seen immediately after the attack) is what can cause damage to the enemy (i.e., he's temporarily invincible).
Effective Unstoppable Air Puffs
If Kirby fires an air puff at a distance (at the extreme end of an air puff's range of effectiveness) at a minor enemy, the enemy will be defeated, but the air puff won't explode on contact.
Flinging Enemies Through Walls
Using the Throw ability, Kirby can throw common enemies, defeated Mid-bosses, and Star Blocks through walls with open space (air / water) on the other side. He must be right up against and facing the wall, then he needs to throw the enemy at an angle parallel to the ground, not up or down. The enemy flies through the other side of the wall, and continues until it's out of range, or hits a barrier (e.g., while flying through the air, or sinking down through the water ((just like when double-Star Spit is used underwater))).
Temporarily-Frozen Boss Sprites
When fighting most major boss characters, Kirby can take advantage of the lag time exhibited by a Boss's sequence of damage-taking. First, the player must inflict damage to the Boss, and then press Start during the Boss' subsequent shaking and flashing (it is best done ASAP); upon exiting the Start menu, the sprite or repetitive action displayed immediately before the Boss's "damage sprite" will often remain unchanging and continue for varying lengths of time, depending on the situation. The only way to observe this is by inflicting the damage and pressing Start right before the Boss changes its movements (an excellent example: inflicting damage and pressing Start right when the battle with Kracko's true form begins, he changes fully into the cloud, and is "fluffing" at his normal rate. The result: for the duration of Kracko's first attack, he will continue "fluffing" at his normal rate ((not his double-time rate typically seen in this electric attack)), until he ends the attack). Hitting the Boss while it's "frozen" nearly always will not hinder the duration of the seized sprite's / sprites' movements (or lack thereof). Using the described technique, Kirby can also inflict the next bout of damage sooner than if the technique had not been used. This glitch can be performed successively on a single sprite (i.e., an already "frozen" sprite can continue to be "frozen" if the technique is used on it). Nightmare's Power Orb and humanoid forms are unaffected by this glitch; Mr. Bright is only partially affected. On very rare occasions, the game may freeze; the system's buttons will have no effect, but the music will continue to play and loop normally.
Whispy Woods' Rotten Apple
Following the same freeze-activation process as described in the preceding glitch: if Whispy Woods is hit right before he makes an attack (it is essential that he takes the hit not during, but slightly before his "Apple Drop" attack), a small, deformed left eye will appear; the finishing touch: a brown, slightly-pixelated apple just right of its center.
Whispy Woods' Multiple Faces
Building somewhat off of the previous glitch, the timing of Kirby's attacks and Start presses can result in several different mutations of Whispy's face. If the aforementioned two-step process is applied at various times, it may briefly result in any of the following (not including the "freezing" of repetitive actions or sprites): Whispy's mouth and / or nose will disappear, both eyes will become enlarged in excess and will be spaced extremely far apart and the mouth placed far to the left on the trunk, and / or the left eye will flatten and tilt (so that it declines to the right) and a brown tear drop will appear at various sizes.
King Dedede's Sky-High Stars
Using the same technique described in the aforementioned "Temporarily Frozen Boss Sprites" glitch, Dedede must be hit toward the endings of his high jumps (excluding the similar hammer attack). Kirby has to inflict the damage when Dedede is about 1/4 of the screen's height off the ground. When King Dedede lands, his impact's resulting stars will be left where his single "frozen" sprite was the previous moment. The stars may still be inhaled or destroyed, and can still inflict damage to Kirby.
Vaporizing Heavy Mole
Heavy Mole can completely vanish without any explosion when Kirby deals the final blow: Kirby must damage Heavy Mole exactly when he opens up to fire his red or bronze Dygclops. The length of Heavy Mole's firing intervals is always erratic (aside from the first Dygclops fired), so this glitch is quite difficult to pull off.
Kirby's Invisible Landing
When Kirby just about touches ground while falling normally (not while floating), the player must press the A button. Performed correctly, the player hears Kirby's landing on the ground, but does not see his landing: Kirby simply inhales some air and floats.
Vanishing Ability Star
When King Dedede falls flat on his face during the boss battle, Kirby can take advantage of a new way to get rid of an Ability Star. Right before the king stands up after faceplanting, Kirby must discard his current ability. The star will be seen only until Dedede returns to his standing position, whereupon the star instantaneously disappears.
The Magnetic 1UP
In Stage 5 of Rainbow Resort, the firing of a cannon leads to a room with four 1UPs. Kirby should float into the double-block-formed corner (as far as he can go) beneath the two 1UPs at the left: If he faces right, he'll automatically gain the left-most 1UP. This glitch doesn't apply to Meta Knight in Meta Knightmare.
Mid-Boss Stationary Slip-Ups
Regarding Mr. Tick Tock and Mr. Frosty, if the former is led to run into the left wall of the arena, he'll not bounce off of it, but will lie in place on his back kicking his arms and legs; the latter will fall on his face in place if he is facing opposite either side wall and is positioned to it as close as possible: when he goes to throw an ice cube, it will drop right to the ground.
King Dedede's Weakling Jump
During this Boss's battle, when the King is floating in the air, Kirby must lead him to the far side of either corner of the arena. If Dedede is as close as possible to the wall, and is at that same time facing opposite the wall, once he exhales and lands, by chance he may decide to jump in the direction of the wall or straight up with his hammer; he will not, however, get off the ground (partially, in rare instances). He will not move either left or right while jumping, nor will he return to normal if Kirby damages him. Dedede returns to normal if he is made to move away from the wall or performs his tackle into the wall. If he doesn't perform the tackle in any of the first five of his attacks, he will inhale as usual, but will not get off the ground: he will sit on the ground with dust puffs underneath him when he should be initially floating into the air, preceding his "float chase". After this, the floating King Dedede will chase after Kirby as normal.
Extreme Speed in Water
Using the Backdrop ability into a body of water when grabbing an enemy, Kirby will hit the water's surface and speed along in the jump's direction (pressing the A button ensures a super-high jump when using Backdrop); holding the A button (optional: use in shallow water) and left or right on the D-pad, the player will allow Kirby to speed through the water. Using one of Meta Knight's attacks (the Meta Chop) repeatedly when going into water also yields the same effect.
The Accelerating Flying Mr. Tick Tock
Kirby can send this Mid-boss flying back at increasing speed once dealing the final blow. When Mr. Tick Tock charges Kirby, he will occasionally slide into Kirby while performing his alarm-clock-like attack: he must be hit right when he begins to slide.
Waddle Doo's Erratic Beam Attack
Using Backdrop's rush-and-grab attack, Kirby should grab a Waddle Doo while it is in the middle of performing its beam attack; this may be done from either side of the Waddle Doo. The current beam attack will cease and another will begin anew once grabbed by Kirby.
A Delay in Star Block Busting
Star Bocks can on occasion be found placed right next to either edge of the screen. Facing the edge of the screen, Kirby can perform a slide attack on the very edge of the Block and it will break once the attack is ended; typically, Slide attacks performed off the very edges of any of the types of Blocks will not bust the Blocks.
Backdrop Ability: Rushing Through a Secured Rope
Kirby can dash-and-grab right through the rope located in the very beginning of Orange Ocean's third Stage. Kirby needs to stand on the small block found lining the left side of the pit that's located immediately left of the rope: facing the rope, Kirby can then rush right past the pit, through the rope, and into part of the ship's hold below.
Wheel Through Walls
First, go to Olive Ocean and head to the room containing Bonkers. Super-inhale both Sparky and Sword Knight to make use of the Mix ability; repeat until Kirby gets the Hammer ability, then pound the stake with it. Return to swallowing Sparky and Sword Knight again until Kirby gets the Wheel ability. Now, have Kirby move up to the point where the screen scrolls towards Bonkers, face left toward the chasm, change to Wheel form and change back right when Kirby gets off the edge. Kirby will now be inside the walls; while floating, he may travel through the walls by first moving slightly to the right or left and floating up once. If Kirby moves nearly out-of-screen to the right, and immediately when any of the other Kirbys (if they are present) defeat Bonkers, Kirby can continue to float down and through the walls (if the Bomb Block below isn't destroyed). This glitch can be replicated at other Mid-bosses, or with other abilities that transform Kirby besides Wheel.
Stuck and Relocated Flamers
Throughout the game, Flamers can be found in rooms with unique structural layouts. If Kirby bumps into a Flamer while using the Wheel ability (any other ability will also work if it partially damages a Flamer and sends it flying far enough), it can be knocked inside a wall. It can then fall onto and circle around any platform beneath it, whether it be a type of Block, or part of the wall complex (since walls are technically gigantic platforms), etc. It may also simply drop out of sight, as is seen especially in one of Rainbow Route's rooms that's full of Star Blocks. Another type of Flamer will temporarily float and follow Kirby relentlessly upon being partially damaged: when following, if this type of Flamer has a solid barrier between it and Kirby (standing right up against the barrier), it will vibrate erratically. The Flamer can be made to vibrate in different directions, depending on how Kirby leads it upon damaging it: most of the time, the stuck Flamer will not harm Kirby.
Dark Mind's Hats
First, beat Dark Mind's eyeball form. At the last second, call the other Kirbys. Make sure one of them has the Sword, Bomb, Missile, Beam, Fire, Tornado or Laser abilities. Once all the Kirbys hop onto their own Warp Stars to fight Dark Mind's final form, their hats will be on the top-left corner of the star. With Missile, though, it will be on top of their heads.
Kirby's Friends' Long-Lasting Hats
In both Boss Endurance and the main game, once Kirby defeats Dark Mind's giant eye form, the player must press the R button just as the screen goes completely red; one or all of Kirby's friends may arrive. Each one that arrives comes with his current ability and its respective hat and / or weapon. Occasionally, an item will come with them, too. Most of the time, they will move freely throughout the following cutscene, always without interference (sometimes, they may move around a bit and then line up in formation). Only those that are standing still, as normal, will get Warp Stars in that cutscene. All those who got "left behind" will still arrive with their respective Warp Stars in the final battle. Most of the time, the hats and / or weapons will carry over into the final battle and be seen with their respective Kirby. Some Kirbys may come with certain abilities, like Fighter in particular, that will render themselves invisible during the final battle with Dark Mind's unstable, third form: a blank Warp Star will be seen moving around and shooting projectiles as normal. Occasionally, this glitch will freeze the game right before the final battle.
In some areas in the main game, the first room via Carrot Castle's castle door entrance in particular, Blockins can often be found in close proximity to ladders. Kirby should push the Blockin into the ladder through the use of an ability or simply allowing it to attack him. The Blockin will return to its Star Block form, and Kirby may casually approach the enemy; if the enemy is positioned partially on the ladder, Kirby will be able to cling partially onto the ladder's open side and usually proceed downward or upward in the same longitudinal postion. Worthy of additional note, when climbing any ladder, Kirby is able to climb up past the point where the ladder ends; Kirby may protrude past the upper rung significantly and still be invulnerable to damage incurrable from enemies above.
The Levitation Glitch
Kirby has to battle Dark Meta Knight before fighting Dark Mind. When Kirby strikes the final blow, he must float to the top of the screen and stay there. Dark Meta Knight will shatter and Kirby will fall to the bottom of the screen, bounce off the ground, and levitate. This glitch can also be induced by using Smash's Final Cutter attack and the same move in the Sword and Master abilities. Use the attack just before Dark Meta Knight shatters, and Kirby will fly way up, and end up levitating at a much higher level than strictly by bouncing. In Boss Endurance, Kirby can get the UFO ability via Mix from various Bosses (inhaling multiple mini sharks that follow after Gobbler as he charges from off-screen at Kirby, Bombar's dual-missile attack, etc.), and keeping it to the end of Dark Meta Knight's battle will automatically levitate Kirby at any part of the screen when Dark Meta Knight shatters. In any case, the levitational effect will cease when Dark Mind's portal appears.
Ability Star Through Walls
Kirby (with a Copy Ability) must stand in front of a door that can be opened by a switch. However, for this glitch to work, the door must be shut. Kirby must face away from the door and drop his ability. The Ability Star will bounce through the wall onto the other side.
Kirby needs the Master ability for this glitch. Fight a Boss and lower Kirby's hit points to around 2. Then, call the other Kirbys and get rid of the Copy Ability and leave it bouncing around. Have Kirby quickly die in the fight, then return to the Boss arena. If done correctly, Kirby's friends should still be heard and seen fighting the Boss while Kirby's not in the Boss's arena. This glitch only works against Moley, Kracko, and Gobbler. Left in any room, the Master ability (or any discarded ability) will remain there indefinitely (in the Ability Stars' case: only until it breaks), so long as any of the other Kirbys are still in that room when Kirby re-enters the room.
Stuck in Snooter
Kirby needs the Smash or Stone ability for this glitch. Find a Snooter and have Kirby call his friends (any number of them will do), then have Kirby turn into stone with Snooter directly in front. The other Kirbys will sometimes walk in front of Kirby and the Snooter will swallow the others. Snooter then goes into his spitting movement, but nothing will happen and he can move naturally. The player can see the swallowed Kirbys floating behind the Snooter. After a while, all the Kirbys will fly out at the same time from Snooter in the direction they were swallowed in. This glitch is rare, so it may take a few tries to pull off.
Master Hand's "Triggered" Freeze
In Candy Constellation, en route to Master and Crazy Hand, the player will fight Master Hand alone. There is a pit with a covering of a few Star Blocks just to the right of him. While he's on the right side of the screen, the player should defeat him while he's high in the air and / or as far right as possible (taking advantage of his Burning Finger attack is best for meeting both of these conditions). If Master Hand is defeated correctly, he'll fall toward and into the pit on the right. Alternatively, if Kirby defeats him while he's high enough in the air and farthest to the right, he will land on the Star Blocks; then the player can shoot air puffs at the Star Blocks underneath him, and he'll fall into the pit. If the player waits, he / she can hear a Mid-boss's explosion and its "trigger" before it. When the "trigger" sounds, Master Hand will freeze at whatever altitude he is falling / resting at and then explode (the player can thus see the "freeze" effect if he/she carefully times the destruction of the Star Blocks). The "trigger" undoubtedly possesses this levitational effect; the "freeze" effect is only clearly observed in this particular Mid-boss battle with Master Hand; however, this "freezing" phenomenon is likely applicable to all defeated Mid-bosses.
Push Past Water Current Barriers
Kirby will need the Missile ability. A tower section exists inside the ornate castle entrance in Peppermint Palace. Climb to the very top, and on the right, a Blipper trapped above and a Heavy Knight underneath will be seen. Destroy the barrier that's holding back the water and the Blipper. Kirby must then fly up the waterfall, landing right in the little pond above. This trick can also be used in Radish Ruins in the horizontal water tube; there's a large navigatable space to the right, but there is an invisible barrier that cuts Missile Kirby short. Unfortunately, repeatedly down-thrusting with the Master ability (this technique can be successfully used against other water current barriers) while moving to the right in this area also doesn't work. However, this technique of the Master ability is always the quickest way to move through any space of water in this game.
Falling Through Walls
In Candy Constellation, there is a room in which a small switch is in the center supported by three Stone Blocks with a Sir Kibble to the left and two Rockys to the right. Kirby should stand on the platform above the switch and walk (not dash) to the left off the platform. If the player constantly holds the left button on the D-pad while Kirby is walking and falling, Kirby will fall through the wall's horizontal-decline junction below. This works for the junction on the right of the platform, too, but the player has to use the "float and spit an air puff" process, instead of walking off the platform.
Kirby's Amazing Burning Colors
Right after beating Dark Meta Knight in his true form, just before he shatters, Kirby must use the Burning ability's Flame Tackle. Kirby will fly forward, and when he stops on the ground, his body will be any one of several flame-colored palettes! Unfortunately, the colors will only last about one second.
Reverse-Direction Ice Cube Attack
Use the Ice ability's attack on something freezable, and while it is being frozen, quickly inhale and shoot the air puff through it. If the air puff is touching the other side of the ice cube when the cube completely freezes, the air puff explodes and sends the cube flying back towards Kirby. The reverse-advancing ice cube still remains effective against enemies.
Dark Meta Knight's Straight Ricochet
In fighting both his true and masqueraded forms, Dark Meta Knight can be made to fly backwards straight through the air. Right when Dark Meta Knight's in the process of landing on the ground after having jumped, Kirby must slide at him so be bounces back off the Knight. Occasionally, at this time the Knight will have made the attempt to flip-jump backwards in a blur. However, when Kirby slides into him, Dark Meta Knight (as well as Meta Knight in other games) will then jump above Kirby and try to down-stab onto him (this is a common component of both the Knights' battle procedures). In the combination of his trying to jump backwards and jump up at Kirby to down-stab, Dark Meta Knight will exhibit this glitch. From anywhere on the ground, he will fly straight backwards (frozen in his jumping posture), in a blur at an angle towards the wall. He often leaves a star on the wall, like he normally would if he wall-kicked, but in battling his true form, sometimes he will just bounce right off the wall to the ground without leaving a star. Upon glitching, he'll also sometimes decide to wall kick and fly up and out of the screen's view, making it trickier to predict where he'll land.
Cross the Wind Tunnel Without the Bridge
In Radish Ruins, along the canyon path (in the room with the cannon and a Jack at the end of it) there is a room with a pit that leads to a treasure room. A strong wind to the right is blowing down into spikes and Kirby is normally supposed to hit the Bomb Block above to activate the bridge. This process can be bypassed simply by constantly holding up and right at the same time on the directional pad. Doing this, Kirby will float into the wind, not be harmed by the dangerous spikes beneath, and reach the treasure chest on the other side. Kirby can cross and not have to call up his friends or have a specific ability to activate the bridge.
The Safe Corner of the Arena
In Boss Endurance (and in some places in the main game), when battling Boxy, stand at the very left edge of the screen. When Boxy tries to ram into Kirby, she'll ofttimes miss him completely and smack into the wall. Most of the time, Boxy won't inflict damage, even if Kirby is holding something in his mouth, inflated, standing normally, dashing / walking into the wall, or crouching. If Boxy jumps at Kirby right onto the wall boundary and immediately rushes forward, she'll smack into the wall and damage Kirby (even if Kirby possesses the Mini ability).
The Hovering Bronto Burt
In Cabbage Cavern, there is a room that has a spike maze with a Sparky at the bottom and Flamers running the length of the spike maze (above this room is the room with the Heavy Knight, Sparky, Gordo, and the UFO enemy). At the bottom of the maze room, stand on the ledge between the Sparky and the spike mat. A Bronto Burt will come sailing down at Kirby from the upper-right side of the screen. Kirby must crouch where he is, and the Bronto Burt will end up hovering directly over him until it decides to fly away; otherwise he'll ram into Kirby.
A Flamer Stuck in the Air
In the room described in the above glitch, "The Hovering Bronto Burt", Kirby should enter it from the upper-left mirror; a Sparky is at the very entrance, and Kirby must obtain the Spark ability. Heading down through the maze, Kirby will find two Flamers: he must use Spark to destroy the center-screen wall protrusion's Star Blocks before the top Flamer rounds its first corner. The Flamer will take no damage, stop mid-air, and spin normally just below the ceiling spikes. It is essential that Kirby times this correctly: he should head down to the Flamers at a constant pace all the while, as this is the only known way to accomplish it. Duplicating this glitch in other areas of the game has yet to be proven.
Blippers' Star Block Breakout
In Olive Ocean, in the second to last room before Gobbler, two Blippers are stuck in a diamond-shaped mass of alternately-spaced Star Blocks near the end of the room. Destroy all the Star Blocks except eight (one block positioned on each side the Blippers). Stationing Kirby directly underneath and / or above both Blippers, wait approximately five seconds. At this time, the angered Blippers will break out of their Star Block prisons and pursue Kirby. (If the player has waited at a distance for about 30 seconds, the Blippers won't break out; they are actually trying to retreat from Kirby)!
Fighter's Platform-Penetrating Down / Sky Kick
There are certain platforms that allow ready access to lower levels (e.g., platforms in the intermediate rooms in Boss Endurance). Holding down on the D-pad, the player must press B the instant Kirby passes downwards through the platform (not sooner, as this will activate Kirby's Slide Kick). Kirby's Down / Sky Kick will be activated; if there are any of these permeable platforms in the line of the attack, Kirby will not land, but will pass unheeded through each platform until a solid surface or water is reached.
Fighter's Strictly-Downhill Aerial Spin Kick
Certain slopes in the game are at a low angle of incline / decline; a slope of a specific angle is necessary to perform this glitch (e.g., the long, grassy platform right beneath the overhanging rock slope with the Roly-Poly, to the left of the trapped Sword Knight and Rocky; found in the Cabbage Cavern room that contains the following: a huge water column moving upwards on the right and a treasure chest at the very top of the room). As typical of all stationary elements in the game, there are "joints" (vertical lines that form from the joining of two identical tiles; e.g., a vertical line in a brick wall/floor) in these slopes. The player has to stand on the slope, facing downhill, so that the "joint" lies directly beneath the base of Kirby's larger foot. With precision, he / she must cause Kirby to perform his Aerial Spin Kick. Kirby will "hug" the ground as he moves down the slope, instead of spin-kicking into the air. This "hugging" is normally achieved by performing the same attack into an upward slope that then immediately shifts to a lower angle. Also, concerning all viable platforms that have multiple joints: every other joint does not work to activate this glitch.
Terminal-Bounce "Skid" Sound
Bounce off a slope of sufficiently-high angle by falling from high up. Kirby must bounce in an arc off the slope, so he must fall straight down. Near the end of Kirby's bouncing in an arc, the player should hold left or right on the D-pad, as the case may be; hold left or right in the direction opposite the arc's path (e.g., if Kirby arcs through the air to the right, the player must hold the left button on the D-pad). At the end of Kirby's spinning, the player will hear the "turning / skid" sound (encountered when Kirby changes direction while walking / dashing on ground) while Kirby is still in the air.
Dark Mind's Energy Beam Echo
When fighting Dark Mind's "giant eye" form, the player must deal the final blow to Dark Mind's while he is firing the massive energy beam. The beam's audible sound effects will continue for some time, even though the battle is over and the beam itself is non-existent.
Dash Sound While Crouching
Dash and immediately crouch so that Kirby falls to a solid surface below (or jump and land on the ground); hold left or right (as well as down) simultaneously, during the landing process (this is essential). Upon landing and crouching, the "dash" sound effect is heard. This glitch does not occur in Kirby: Nightmare in Dream Land.
Kirby's Unbreakable-Block Bounce
Kirby can bounce off Star Blocks, Bomb Blocks, and others without breaking them. He must fall onto them from the air at the very minimum height required to face-plant.
Bomb Ability: Sound Transfer
The player can hear Kirby's bombs' explosions from a room next to the one the bomb(s) is / are thrown / placed in. Firstly, any number of Kirby's friends must be in view. Secondly, Kirby should throw / place a bomb. Thirdly, well before the bomb explodes, Kirby must immediately exit the room. If Kirby's friends have not moved out of view (in the room on the other side of the mirror), and the bomb has not exploded before Kirby left that room, the player will hear the explosion while Kirby is on the other side of the mirror.
Bomb Ability: Instantaneous Double Depth Charge
While in the air over a stretch of water, Kirby must plant a bomb mid-air. If Kirby times the planting correctly, so that he and the bomb hit the water's surface exactly when the bomb starts to drop in the air, two bombs will be produced in an instant. Worthy of mention, Kirby's performing this while moving left or right in the air will result in a bomb x bomb barrage mat.
Bomb Ability: Color-Changing Waddle Doos and Switch
In the room with the large Heave Ho Block standing in the way of the mirror that leads to the Chalk Spray Paint, there are four mirrors. The one in the upper left hand corner leads to a room which contains a Droppy. Waddle Doos and / or the small switch must not be visible in order to result in a color-change. Kirby must have the Bomb ability and allow the Droppy to steal it; Kirby must then allow the transformed Droppy to blow up, as the glitch will not work if Kirby hits the new Foley with an air puff. Depending on the vertical location of the Foley is when he drops, the visibility of the switch or Waddle Doo(s), and possibly the horizontal location of the Foley, the result of the explosion is varied. The Waddle Doo(s) and / or the door switch will stray from their typical palette color patterns: the switch may be a bright gold and brown color, a faded typical color palette pattern, or a dark red and gray color; the Waddle Doo(s) will vary from being outlined in sky blue and bright red to a dark, faded variation of the typical color palette with green; also, the beam they attack with may be of the standard yellow color or a dark and faded red. The glitch's effects will not disappear until Kirby leaves the room.
Bomb Ability: Color-Changing Snorkel Mask and Spray Attack
There is a room in both Peppermint Palace and Cabbage Cavern that contain a Droppy, as well as a body / bodies of water. Here, Droppy must be allowed to steal Kirby's ability and change into a Foley. The Foley must be allowed or caused to drop and explode. This results in different colors of masks and spray attacks when in the water. Kirby and his friends can have green masks which spray green and yellow water, pink masks that spray pink water, golden masks that spray yellow water, or yellow masks that spray black water (reminiscent of crude oil). In Cabbage Cavern, a delay in color change to green will often occur until Kirby plunges deep enough into the water, closer toward the Blipper. His friends need not be present at a Droppy's assimilation for the glitch to apply to them: they may simply be called up.
The player should press the A button to ascend while floating; he / she must press it repeatedly as fast as Kirby will allow. If pressed in short-enough intervals, one or more "silent floats" will be performed in succession; Kirby will flap his arms and climb higher, but no sound will be heard. These "silent floats" are also observed in Kirby: Nightmare in Dream Land, but only by the player's continuously holding up on the D-pad.
Scatter Dark Mind's Mirror-Spawned Enemies
In fighting Dark Mind's giant eye form, he'll occasionally sweep one or both of his mirrors across the screen. When the mirror(s) make(s) its / their final pass, it / they will spawn three enemies (six, if one validates the possible combinations of three Parasol Waddle Doos, Sir Kibbles and their blades, etc.); during this third pass (or occasionally, a single pass), before the mirror(s) produce and drop the enemies, upon hitting the mirror(s): the enemies produced will often be teleported from their original drop zone to a new drop zone (sometimes far outside the screen). Applying the Master ability's "up-thrust" attack is the easiest way to activate this glitch.
Teleporting Mini Sharks via Pummelling
Using Fighter's (or any other ability's attack(s) that shoot(s) enemies up into the air without killing them) mid-air windmill kick, drop onto a mini shark when battling Gobbler. The little sharks will pop out of the water, but instantly return to their original position in the water; they will not fall into the water with a splash, but "teleport" right down into the water.
Gobbler Floating Down in the Air
Defeating Gobbler while he jumps out of the water will cause him to sink (not fall) through the air; this "sinking" is the same speed as when defeated in the water.
The Weakling Bronto Burt(s)
Upon defeating Wiz, if one or more of the Bronto Burts he produced are still flying around, Kirby can just run into and damage them without taking damage himself.
Master Sword's Fiery Sheath
Kirby must be possessing the Laser ability. In the very beginning of each of the four battles with Dark Mind, the Master sword stands by, ready to be wielded by Kirby. Kirby must fire a laser beam while he comes in contact with the sword. The flashes of light produced by Kirby's head apparatus will immediately change into flames. This "stand" of flames is visible only during and shortly after the gaining of the Master ability.
When about to activate a big switch, inhale using the Throw ability. If the B button is still being held after the cutscene, no sound of inhaling will be present. This glitch does not exist in Kirby: Nightmare in Dream Land.
Extra Puffs of Dust
During uninhibited dashing, every fifth second will yield an additional puff of dust.
Inaudible Warp Stars
During the cutscenes that appear while using Warp Stars, the player may press Start and return again to the cutscene; the interrupted sound byte will not be heard until it has finished playing.
Dual Death: Pseudo-Ghost Kirby
Kirby must possess the Cutter, Bomb, Laser, or Cupid ability while fighting Dark Meta Knight's true form; Kirby must have one hit point left, and Dark Meta Knight must have an amount of health left that is sufficient to deal the final blow with the abilities' projectile(s). When Dark Meta Knight preps his Mach Tornado and sends it flying at Kirby, Kirby must fire the projectile so that it hits Dark Meta Knight while Kirby is sucked up in the Mach Tornado; both Kirby and Dark Meta Knight will die practically simultaneously, the screen will turn black, then white, and the battle will begin again. This time, Kirby and his friends can pass through Dark Meta Knight's person and attacks without taking any damage whatsoever (for the duration of Kirby's temporary invincibility at the beginning of the battle, however, Kirby can actually take damage); any attack Kirby uses will be of effect, either damaging the Knight or not harming him (air puffs and standard slide attacks). When Kirby defeats the Knight, the unofficially and aptly named Pseudo-Ghost "ability" will be lost.
Dual Death: The Invisible Mirror World
Kirby and Dark Meta Knight must both be defeated in the same manner as described above in "Dual Death: Pseudo-Ghost Kirby". The only difference, is that this process must be repeated with Kirby starting the battle with no lives left. Upon dying and automatically returning to his spot beneath the Dimension Mirror, Kirby and his friends will be invisible, as well as all the following: mirrors, stars resulting from contact with solid surfaces, water splashes, blowing air, cannons, Warp Stars, Copy Pedestals, stakes, switches, Heave Ho Blocks, switch-and-handle activated doors, discarded abilities, platforms hung on ropes, Kirby's friends' status markers (top left of screen), the Kirbys' cell phones, nearly all attacks (e.g., Crash's ending flash is visible, Meta Knight is seen through Magic, etc.), Treasure Chests and their contents, stationary Mid-bosses, moving parts of Bosses (King Golem's stationary hand and body remain visible), and the minor enemies. Per successful glitch attempt, recovery items are very rarely visible. Mirror entrances are often seen to either remove secondary backgrounds (e.g., top and bottom mirrors in the Olive Ocean room that leads directly back to the main room containing the Dimension Mirror) or are a particular color (often red or blue) or shape (arched door that comes to a point). The animation of any Blocks' destruction is rendered non-existent; it simply disappears when destroyed. All things invisible still interact with each other as they normally would. Thus, a good memory of where enemies and mirrors are located is essential for long-term exploration of the "Invisible Mirror World". When Kirby dies, defeats a Boss, uses the Magic ability (excluding the Mix option gained from the roulette), hits an enemy with the Hammer ability's Hammer Flip or even when a Bomber explodes, everything will become visible again.
Parasol Ability: Automatic Crouch n' Slide
Kirby should drop down onto a solid surface from the height of one Star Block; then, he'll touch ground and automatically move a short distance in whichever direction he's facing when he lands. This glitch isn't present in Kirby: Nightmare in Dream Land.
Involuntary Directional Change
When walking on icy surfaces, Kirby can crouch and face the opposite direction in which he is moving; when Kirby stops crouching, instead of walking backwards, he'll instantly switch direction and walk in the direction of the slide. Regarding the same glitch, Kirby "moonwalks" in Kirby: Nightmare in Dream Land.
Edge-Penetrating Reverse Jump
When walking or dashing, Kirby must jump and, by skillfully tapping the D-pad, immediately face the opposite direction of the jump. This must be done into a flat, open-topped solid surface (for example, a Star Block or ledge). Contact with the vertical surface must be made close enough to pass beyond the horizontal surface (underside/topside). If performed correctly, Kirby will pass (upward, in the direction of the jump) through the edge of the surface, and onto the immediate surface below. This glitch cannot be performed if Kirby jumps face-first into the surface: he has to jump backwards. This glitch also does not occur in Kirby: Nightmare in Dream Land.
Recoil-Free Slide Attack on a Switch
For all small switches, if Kirby is close enough to one and performs a slide attack, Kirby will not bounce back off of it, but will go straight through.
Double Star Block Inhale
If any item is sitting on a platform made of Star Blocks, Kirby can inhale the item as well as a couple Star Blocks at once! Standing on or near the platform, Kirby will inhale two Star blocks simultaneously: this obviously results in a doubly-powerful Star Spit attack. This is an extremely rare glitch to encounter.
Stubborn Star Blocks
Kirby should stand so that there are two "block lengths" between him and a Star Block; Kirby must be positioned perfectly on top of the "block" and a then move a tiny bit to the left. Kirby must be facing left. Upon inhaling, the Star Block(s) will not budge until Kirby achieves a Super Inhale. In Kirby Super Star Ultra, this is also seen if Kirby quickly switches from an using attack to inhaling a Star Block, and is positioned reasonably distantly: the Star Block cannot be inhaled unless another, normal attempt is made.
Underneath the Dimension Mirror lies the Master ability. If Kirby's friends follow him, they can cover up the Master ability lying there. If enough of the Kirbys are crowding there, Kirby can occasionally walk through his friends and right past the Master ability without gaining it (assuming Kirby possesses no current ability).
Hot Head's Crack-Penetrating Fireball
Kirby should be standing on a slope and persuade a Hot Head to fire its long distance attack. If the fireball hits a junction between two "blocks" or "tiles" (a group of pixels of a fixed size used to create the appearance of a certain environment such as a wall, ground, etc., usually repetitively placed next to each other), it will in rare instances travel down a "block's" length into the crack.
Gobbler's Frozen Face
If Kirby inflicts the final blow while Gobbler's face is scrunched up, when he's preparing his quadruple-consecutive-charge attack, his scrunched face will freeze like that. Gobbler will then slowly sink and explode.
Kirby's Current Ability... in Name Only
In Olive Ocean, a room contains a dry cave with a Bomb Block in the center of the floor; two Waddle Doos stand above it on a platform, and a wandering Droppy explores the whole area. Kirby must go into this section with any ability, and should stand close to the Bomb Block: when the Droppy comes near, he should destroy the Bomb Block and then let the Droppy try to take his ability. The Droppy and Waddle Doos will drown and Kirby will be left with no ability, save its title in the bottom left hand corner of the screen. Its description will not appear. The title will change if the player accesses the Start menu, obtains a new Copy Ability, or is damaged. The U.F.O. ability's lasting title can still be kept while in the central room of Rainbow Route (the one containing the Dimension Mirror).
In rooms where Snooters and pits are both present, Snooter will delay an unfortunate Kirbys' demise for a second or two: when Snooter falls over a pit, Kirby can get caught in his mouth and will only die once Snooter spits him out... deep in the dark of a bottomless pit.
Mr. Frosty's Teleport
When battling Mr. Frosty, Kirby should first lead him to the very edge of an arena (with no barriers on the sides). Facing away from the wall, Mr. Frosty may decide to charge at Kirby: he'll go out of screen and right when he charges forward, he teleports forward to his edge of the screen.
Heavy Knights Isolated on Edges
Using an ability that will partially damage a Heavy Knight and send it flying, Kirby can hit any of these Knights so that they land on the extreme edges of platforms. Heavy Knights will not be able to move toward or away from Kirby once they are at a certain point on the very edges of platforms; they will appear to be floating over the free space that lies past the edges of platforms: too close, and the Knights will still be able to walk; too far, and they will fall off the edge.
"Giant" and "Heavy" Enemies Cloned
In a room in Rainbow Route, a Heavy Knight will appear mid-air and land onto the platform below if the first is defeated. If Kirby moves far off screen, but not enough to cause the new Heavy Knight to disappear, he can move back, and the first Heavy Knight will have respawned. Two Heavy Knights will then be visible together. This presents a perfect opportunity for Kirby to Super Inhale the Knights and gain the Mix feature. This glitch is also applicable to the Giant Rocky found in a room in Moonlight Mansion.
Temporarily Modified Views of Arenas
Using the Cook or Magic abilities, Kirby can with great ease change the viewable area of arenas during Mid-boss battles. Using Magic or Cook (repeated used is possible, so long as no pre-battle enemies are in view) during the point in which he is immediately "sucked" into the battles, Kirby can gradually change the viewable battleground: the Mid-Boss will always be able to freely move about during these ability-induced pauses in the battles.
Invert-Colored Waddle DooIn a room in Rainbow Route, a Waddle Doo will have a chance to appear as a different color. It is unknown how it can be done.
Find a time bomb. Plant it in the middle of where all the machines would be in Free Run. Then, go to the openings to the underground at the city and have Kirby stand on the ledge. (Not too high and not too low, but in the middle). Jump on the ledge and move a little bit towards the gap so the middle of Kirby's body hits the ledge. When done correctly, it should make Kirby fall slantwise after he hits the ledge of the slanted wall. Kirby should then proceed to fall to the ground. After doing this, Kirby must not jump or get into an Air Ride Machine, because it returns him to normal. Have Kirby make his way to the time bomb and get hit by the bomb. Kirby should now perform his hit fall animation while on the ground, which makes it look like he performing a breakdance. Getting Kirby hit after this stage will not stop his animation. Kirby can also be sent into his spinning state if he is hit by an opponent's machine with high offense, such as the Hydra.
After performing the above "Breakdancing Kirby" glitch, Kirby will begin twitching if he (or a nearby CPU or player) uses the Mike ability.
Out of Bounds
Pick the Dragoon. Fly to the invisible wall next to the castle and continue bashing it. (Or, if flying high enough, Kirby can pass right over the wall.) If done correctly, Kirby will break through the wall and start shaking. At this point, the pink dot on the minimap that represents Kirby is out of the playable area. However, eventually another barrier will block his path.
This glitch is most easily performed in time attack mode of Checker Knights. In the 3rd lap, small Gordos and a Wheelie Bike appear every few seconds. To do it, have Kirby obtain the Wheel ability, and hold down the A button when Kirby gets near enough to the Gordos (not too close). While the thunderball is operating, Kirby stays in wheel form, long after the time when he should return to normal under usual circumstances.
Infinite Flight Glitch
A glitch can make the Bulk Star capable of infinite flight distance. In the Stadium Air Glider, choose the Bulk Star and hit all the boost pads; as the Bulk Star takes off, quickly tap the A button. Normally, boosting in mid-air with any other machine would cause the character to drop to the ground. However, under these circumstances, the Bulk Star will forcefully vibrate up and down and maintain altitude. This can allow the player to reach the end of the track, which is just around 4,500 feet. Alternatively, a player can use a turbo controller, set the turbo to the A button, and simply hold the button. The Bulk Star will rapidly ascend to the ceiling if this method is used.
Camera View Glitch
While playing City Trial, go onto a Super Boost Ramp and pause as soon as Kirby touches it, and move the camera view with the C stick. The camera will turn in a circular motion instead of left and right. This can also be done in Celestial Valley when Kirby is climbing up the waterfall.
Top of the World
This glitch requires at least two players. While playing City Trial or Free Run, have Player 1 have the Hydra, and Player 2 have no vehicle. Go to the Highland Plains, near the golf holes. Have Player 2 float above a golf hole, and Player 1 go in the hole. If Player 2 gets hit by Player 1, Player 2 will go flying straight upwards until he hits the vertical barrier. Then, Player 2 will float in place for about 15 seconds, and then begin to fall down.
Kirby's Long Fall
In the first Destruction Derby, there will be two pits covered with rocks. The player must destroy one of these rocks so that a pit will be exposed or wait until a CPU (or human) player does it. The player must then have Kirby lose all health and die right above the pit (this is best acheived using the Golden Spikes / Gordo item close to the pit). If done correctly, Kirby will fall for longer than he would if normally fell down the pit and an otherwise unused "impact" warning complete with an again otherwise unused "alarm" sound effect for about a second.
Select the Silent Seabed level and go up to the part with the wall that has to be tapped three times to be rid of. Kirby needs his Stone ability to perform this glitch. While in Stone form, roll up to the wall and it should appear to be destroyed and become passable. However, if the player taps the area where the wall once, it would apparently seem that the game did not register the wall as being destroyed already. The invisible wall will still require three taps to be rid of completely.
Sinking Maxim Tomato
To perform this glitch, Kirby needs the Ice Bomb power. Have Kirby go to the first stage in Prism Plains and walk until he reaches the pool of water with the Maxim Tomato in it, then have him throw the bomb at it. When the bomb explodes inside the pool and freezes the water, the tomato will slowly sink into the ground. Going into the water and breaking the ice blocks will cause the tomato to pop up again and behave as though nothing had happened. If Kirby does nothing, however, the Maxim Tomato will fully sink into the ground and disappear. When Kirby walks away from and then back to the pool of water, another Maxim Tomato will appear.
Distilled Throw Power
To perform this glitch, Kirby needs the Throw ability with its respective Ability Scroll. Upon entering the battle with Mrs. Moley, when she pops out of her hole, have Kirby stand next to her, facing away. When she starts throwing things, have Kirby inhale until he inhales something. If Kirby simply stands there and does not throw the inhaled item, the held item will damage her. If Kirby K.O's Mrs. Moley in this manner, the inhaled item and its glowing aura will both disappear and the usual whiteout ensues. When it is over, Kirby will get rid of the item automatically by throwing a glowing ball of energy.
To perform this glitch, Kirby will need the UFO ability. If Kirby gets killed by Bohboh as he throws him into the lava pit in the center of his room while he has the UFO ability, the colors of Kirby's body and feet will considerably lighten. He will be covered in strange pale lines similar to the panels of Metal Kirby.
Ghost Through Walls
Kirby needs the Ghost ability for this glitch. Pick any area where there is a Sword Knight, Metalun, or a Heavy Knight standing on a slanted platform with a wall at the end (ex. Stage 4 of Nature Notch). Have Kirby possess the enemy and have it slash at the wall. If done correctly, Kirby will now be inside the walls. He can freely roam around and in most cases can return to the level with no side effects and end the glitch, but he will be permanently trapped inside if he ditches the Ghost ability. Getting a Bun to throw Kirby into a wall when he is right next to one of the said enemies will also cause the glitch.
With the Ghost ability, control Acchi. Next, double tap left to have it slide a little bit, then jump. If done correctly, Acchi will fly across the screen for as long as the A button is being tapped.
Ability Through Walls
When the screen gets automatically scrolled like in the rooms right before Dark Nebula, or due to a Mid-boss battle, bubbles and ability stars get pushed into the current screen even if there's a wall, similar to the "Wheel Through Walls" glitch from Kirby & the Amazing Mirror.
Beam Sound Carry-Over
If Kirby enters a door while a Waddle Doo is using its Beam Whip attack, the sound of the beam can be heard during the transition from that room to the next.
Find an area where two Flamers can be on the screen at the same time. Destroy any blocks keeping them from full freedom of rolling. If done right, the first Flamer will be rolling while the second is floating above it. If it hits a wall it just bounces right off, too.
Moving Copy Glitch
Go to the second stage of Secret Sea, after the Warp Star. This glitch can be performed with either the Sir Kibble or Acchi. Inhale and swallow one of them quickly As Kirby is copying the power, he will be moving until he reaches the wall.
Spark Ability: Two Attacks at Once
Kirby will need the Spark Ability and its respective Ability Scroll in order for this glitch to work. The player must have Kirby charge up to full power, tap the B button, and immediately afterward hold left (or right) on the D-pad and the B button. If done correctly, Kirby will perform his fully charged electric barrier and his long-range attack at about the same time. The graphics surrounding Kirby will glitch for a split second, but there are no adverse side effects. Under normal circumstances, Kirby would have to recharge after performing either attack, but through this glitch, he no longer needs to, although the timing can be tricky.
Superspeed Waddle Doo
Either the Copy or Bomb copy ability is needed. Head to Skyhigh in Milky Way Wishes and enter the room in the door maze where a Parasol Waddle Dee and a Parasol Waddle Doo float down. Enter the right-most door to go into the next room, then head straight back into the previous room by going into the same door Kirby appeared out of. Zapping / Bombing the Waddle Doo (who is on the right) and making it touch the platform with the middle door is located will make it run around the room at higher and higher speeds before eventually falling through the floor.
Floating Knuckle Joe
Kirby must go to Aquarius in the Milky Way Wishes sub-game. Kirby must continue through the level until he finds a Broom Hatter with a Knuckle Joe. Past that, he will find another pair of the duo. If the player watches the Knuckle Joe closely, it will sometimes jump on the ledge, and the game will register it as being on ground when it is walking on air!
Weak Hammer Flip
Kirby must take on Hammer ability and go to Skyhigh in Milky Way Wishes. When he reaches Kracko, he must use the Hammer Flip attack at just the right time when Kracko's health bar is filling up. If done correctly, the attack will have done a tiny fraction of the damage it usually does.
Freezing the Game
The Suplex ability is needed. The player must head to Peanut Plains in the sub-game Dyna Blade and continue through the level until he / she reaches the ledge the leads to the Mid-boss battle with Chef Kawasaki. On the opposite ledge, there is a Bomber. Kirby must wait until it is about to fall, then dash grab it. He will fall down into the room, and he should use the Suplex ability's Rock Drop attack (performed with the A button). If the Bomber was grabbed at exactly the right moment, it will freeze the game and cause the buttons to stop responding; the music will keep looping, but the game must be reset to continue playing. It may take a few tries to do this.
Non-ability Waddle Doo
The Copy copy ability is needed. Go to Skyhigh in Milky Way Wishes, and advance until you see the Parasol Waddle Dee and Waddle Doo. Copy the Waddle Doo when it's on the ground, and as soon as you grab the Beam ability, go back to Copy. Keep repeating, and eventually you will take no ability from the Waddle Doo when you beat it.
Puffs of Dust in the Air
Kirby must be made to dash, then turn in the opposite direction. Right when the turn is made, Kirby must jump into the air, and the puffs of dust will still be seen at his feet.
Suplex's Bounce Glitch
When dashing off of a platform, if Kirby is set at a correct distance, he will "trip" straight through the air without falling downward (i.e., an invisible portion of platform appears to continue out a ways, but Kirby trips along straight through the air).
Delayed Defeat of Dyna Blade
If the final blow is dealt to Dyna Blade (particularly in Helper to Hero) during some of her attacks, most notably her "swoop" attack, she will continue to finish her attack without any of the typical explosions seen upon defeating various Bosses and Mid-Bosses. Once the swoop is finished, explosions will be seen as she flees the battleground.
Non-Damaging Suplex Flip
A defeated Mid-Boss may bounce off of the far left side of the screen in The Arena and not take damage. Kirby should perform his Body Slam attack very close to the left wall and facing it: the Mid-Boss (in rare cases) will bounce off the wall, and land on its back without exploding. This phenomenon is also occasionally observed using the Fighter and Yo-Yo abilities' grab attacks.
Yo-Yo Ability: Bury a Defeated Mid-Boss
When a Mid-Boss is defeated and lies immobile on the ground, Kirby should use Yo-Yo's Hammer Drop; the Mid-Boss will in rare instances disappear in the ground underneath Yo-Yo Kirby (or Gim, if playing Helper to Hero). The Mid-Boss will not be heard to explode until its normal "delay-in-explosion" time is expired: only then will the explosion be heard, but not seen.
Invisible Wall Barriers
When fighting any of the Mid-Bosses in succession, such as in Helper to Hero, a defeated Mid-Boss can be thrown a distance using some abilities/characters. Rarely, a thrown Mid-Boss will hit the side of the screen (the side that continues to scroll in the cross-arena direction) while it is scrolling and will drop down onto the ground. Using the Jet ability's/Capsule J2's Rocket Dive on an incapacitated Mid-Boss will occasionally produce this result.
Pass Through Cloth Blocks
The glitch is performed in the Star Shooter sequence of Cloud Palace. There is a spot where multiple Cloth Blocks are stacked on top of each other. Have Kirby shoot stars at the blocks while moving straight forward, then diagonally upwards after colliding with the blocks. If done correctly, Kirby will pass through the remaining blocks into a small compartment and get the Star Bead inside without having to shoot out all the Cloth Blocks. To get out, Kirby can shoot the remaining blocks under him.
A second player is needed to activate this glitch. Kirby and Prince Fluff must enter the battle with Yin-Yarn and wait for the second Soocher attack. While Kirby goes to the door, Prince Fluff must jump to the top of the screen. At the moment Fluff touches the top of the screen, Kirby must go through the door. If done correctly, the Soocher attack will end and the top of Fluff's head will be stuck in the ceiling, thus suspending him in midair! He will be unable to move, but because he is technically airborne, he can still use the Yarn Whip and turn into the Parachute and Weight forms, but he will still be stuck in place. To end the glitch, Kirby must defeat Yin-Yarn alone, and allow Angie to take both of them to a different platform. This glitch also works with Kirby jumping to the top of the screen, and Prince Fluff exiting the door, making Kirby stuck.
Waddle Dee Anti-Jump
At Fountain Gardens (located in Grass Land), there are two Waddle Dees sleeping next to each other with beads over them in the shape of a heart. Kirby must get on both of them, with one foot on the left Waddle Dee and the other foot on the right Waddle Dee. If Kirby tries jumping directly upward, he will still be standing on the Waddle Dees, but his feet will transform like he's jumping! This glitch also works at Big-Bean Vine, using the two Waddle Dees on the ground (the one with the bow and the one cowering in fear).
Kirby must head to Water Land and jump on the whale's geyser. If Kirby stands completely still and waits long enough, the geyser will suddenly disperse. While this itself is not a glitch, something glitchy happens afterward: Kirby will fall a short distance through the air, but his feet will still be in standing position.
Standing on Air
To perform this glitch, Kirby must go to Splash Beach in Water Land. After going up to the clouds and waking up the sun, he must come down and walk through the level until a turtle swimming on rising and falling water is seen. If Kirby gets onto the turtle and stands on it, it looks like he is standing on air at a very small distance from the turtle, rather than on the turtle itself.
Kirby Panicking on Dry Sand
For this glitch, Kirby should go to Stage 9 of Volcano Valley or play Survival Rush. If using the Volcano Valley method, he should go to the room with Buzzy Bat's door and go to the room with Great Gear. If on Survival Rush, he must go to the middle door and defeat any other Mid-bosses until he gets to Great Gear. When Great Gear turns the floor to quicksand, the player should have a Kirby get caught in the moving sand but mustn't let the Kirby sink off the screen. The player has to keep him near the top of the quicksand floor. When the sand hardens and if done just right, the Kirby(s) will still act like they are sinking, even though they are at the top of the floor and not sinking in quicksand. If the player taps the screen while the glitch is in progress, the Kirby(s) will stop panicking.
Note: This glitch does not work on Stage 6 of Sandy Canyon due to the fact that the floor does not turn to quicksand during the first battle with Great Gear.
A Kirby's Silent KO
For this glitch, go to Stage 8 of Sandy Canyon and go to the end of the first room and find the pull ring and the Big Mummbon. Have one Kirby attack the Big Mummbon, one Kirby pulling the ring, and the rest stand where the door is supposed to be at. When the Big Mummbon shoots out a poison blob, make sure the Kirby attacking the Mummbon gets hit, and have the rest go through the door. The Kirby that was attacking the Mummbon will be KO'd, but when it happens, he will not scream.
This glitch sometimes occurs in Kirby Quest; when a certain Kirby is hit by an attack, instead of falling down and turning blue, he will instead fly all the way beyond the top of the screen and not come back down. When this occurs, the player will not be able to advance, and will be forced to go back and start the chapter again. This glitch can also be remedied by turning the DS off and back on.
Big Blucko's Weird Platform
Go to Stage 1 of Volcano Valley. After defeating the first Cryball, the player must make his/her way over to the flaming Snoozroot, then defeat it to move on. The next part takes about five Kirbys or more: When the heroes find Big Blucko, they must wait under the platform. When the titanic monster stops on top of the platform, the player must gather the Kirbys and attempt to drag them through said platform. Blocked by the Big Blucko, most of the Kirbys will fall back to the ground. Occasionally, one (or more) of them will not fall, and will be stuck inside the platform while standing on thin air. The player must tap the screen to end the glitch. A more common result of this glitch is that one Kirby will suddenly teleport to the ground above, appearing to the left of Big Blucko.
Go to Stage 11 of Volcano Valley. Locate one of the mushroom-covered satellites moving up and down in space. Have a few Kirbys swim over to the ceiling above it, then wait. The satellite should move up to the Kirbys and push them into the ceiling without hurting them. The glitch lasts only a second or two, as the Kirbys will be pushed back into real space when the satellite moves down. The glitch is somewhat risky to try, because doing it incorrectly will result in KO'd Kirbys.
Walking on Brambles
After defeating Lady Ivy the first time, return to Sandy Canyon and battle her again. Once she's defeated, flick a Kirby off the left or right side of the screen. He will land on the thorns below but will not be hurt. He can walk around down there until the Kirbys leave the stage through the door.
Sound Carry-Over Glitch
Kirby will need the Spark ability. Right before Kirby gets on a Warp Star, the player must charge up Kirby's barrier. Right when Kirby touches the Warp Star, the player must press the 1 button. He / she will hear both the sounds of Kirby getting on the Warp Star and Kirby's Spark Wave attack.
This glitch can also be done with the tornado ability. First, battle a Sphere Doomer that offers the tornado ability before the battle and defeat it keeping the ability (Stage 1 in Onion Ocean is highly recommended. Instead of grabbing the Energy Spheres, use the regular tornado attack and charge up. Right when the whirlwind attack is used, touch the energy spheres. The player will hear the whirlwind attack sound and the Energy Sphere sound.
Undead Magolor Glitch
There must be at least two players using Kirby, and one will need the Spark ability. When Magolor charges in at the end of his first phase (after losing his star shield), position the Kirby with Spark a fair distance up and to the right from the Kirby with the Ultra Sword, then swing the sword. If done correctly, Magolor's HP will empty during the cutscene where the player needs to shake the Wii Remote. After this, it will act as if the player failed the Wii Remote shake and Magolor will regain one piece of his star shield and begin attacking again as usual, but the background music will be silent, and the players will be unable to move or take damage, forcing the players to use START or HOME to leave the stage. If any player shakes a Wii Remote during the cutscene, the game will freeze.
Frozen Magolor Soul Glitch
Only one player is needed for this glitch—preferably one with an ability with an invincible dashing attack (Ninja works particularly well). Deplete half of Magolor's health and wait for him to use his dark Flare Beam attack. When he tries to ram Kirby from the background, he must hit Magolor Soul with the dashing attack. If done right, Magolor Soul will be frozen in place, spinning wildly until the second ball of energy is offscreen. It is not yet clear whether his hitbox still works while frozen.
Ghost Wings Glitch
At least two players - one as Kirby and another as Meta Knight - must battle Mr. Dooter EX. One player must deplete half of the Boss's health and dodge his first attack. The players must then have Meta Knight and Kirby positioned at a far distance from each other and Meta Knight needs be allowed to be grabbed in the Boss's fist. The usual ball of light will warp to Kirby. The person controlling Meta Knight must press the 2 Button while the Knight is still caught in Mr. Dooter EX's fist. A pair of ghost wings will fly above Kirby until Mr. Dooter EX begins to juggle Meta Knight and his other items. This glitch lasts only a short time.
Kirby should enter Stage 3 of Onion Ocean. After reaching the Copy Essence that yields the Hammer ability, Kirby must take on that copy ability. He must then rush into the waterfall to the right while performing Hammer Throw. If done correctly, Kirby's hammer will appear invisible and may not work when attacks are used.
3D Classics: Kirby's Adventure
Dedede Healing Kirby
When fighting King Dedede in Rainbow Resort, Kirby must be on his last piece of health and facing left. If King Dedede inhales him, turns right, and spits him out, then instead of Kirby losing a life, his health is refilled.
Star Rod Piece, Yet no Dance
At a Boss stage, when a Boss explodes, Kirby can still take damage by running into it. If this happens after collecting a part of the Star Rod, Kirby will take damage before he can begin his dance, and will be unable to beat the Boss stage, because the player has already collected the piece of the Star Rod.
In the Super Smash Bros. series
Kirby's Frying Pan
Pick Kirby and Mr. Game and Watch in the Mushroom Kingdom stage. Have Kirby steal Mr. Game and Watch's power and stand right on the edge of the bricks, then use the B move. If done correctly, the frying pan will stay on Kirby's hand, even after he gets rid of the ability.
Kirby and Jigglypuff (two players) are needed for this glitch. Have Kirby suck in Jigglypuff, then have him float up in the air. Both players then perform Rollout on both the characters. As Kirby falls, both players release Rollout and when the characters collide, Kirby will get somewhat flatter. The glitch can be repeated with Kirby getting flatter and flatter each time.
Two players are needed for this glitch, one of them being Kirby, the other, Yoshi. Have the Kirby steal Yoshi's ability, then eat him with the ability. The player playing Yoshi must then mash buttons and the control stick to have Yoshi break free. Once Yoshi is free from the egg, he'll become smaller. If done over and over again, Yoshi can become as small as a pixel.
To start off, select the Pictochat stage. Go to the right corner of the stage and jump until the falling animation starts and perform the down+B move. Instead of sliding off, the character will be wedged to the stage and it starts to look like an earthquake occurring. This lasts for however long the move lasts. This can also be performed on custom stages if there two regular slopes in two opposite directions, the second slope being one space left and higher up than the first slope. Performing the glitch on the upper slope results in exactly the same thing. This glitch doesn't work on the left side of the stage. This video demonstrates it.
Two players are needed. Have Bowser transform into Giga Bowser. The second player then performs the Kirby Earthquake glitch, with Giga Bowser right next to the corner. Kirby will be stuck forever, and Giga Bowser will continuously take damage.
Two players are needed. Pick Kirby and Olimar, and a large enough stage. Get the smash ball for Kirby and move Olimar far away from him. Then, have Olimar continuously pluck out Pikimin. If Olimar is far enough away, he won't get sucked into Kirby's pot, but his Pikmin will. Have Olimar keep plucking out Pikmin until the pot reaches the maximum number of items it can hold, and it spews out a number of items. (The glitch can be performed by replacing Olimar and his Pikmin with Fox and his blaster)
Bang, Bang, Bang
First, get a Smash Ball for Kirby. Then, have another player grab an assist trophy. Once he has grabbed one, have Kirby start banging the utensils. Kirby will never stop banging until the match ends.
Pick the Bridge of Eldin stage. Then, grab a smash ball for Kirby. Let the bridge be destroyed. When the bridge starts to get fixed, jump into it with Kirby and use his final smash. If Kirby is inside the bridge when it finishes rebuilding, it will push him above it. In the end, Kirby will look like he has a final smash attack when in reality he doesn't.
As of now, the only platform this will work on is the tree from the original Pokémon Stadium. It's similar to the Kirby Earthquake glitch, but only with the Up+B move. Go onto the ledge, then use the Up+B move. The character will become stuck for a few seconds and then get released.
Steal and Warp
The glitch is performed on a stage where there are two solid platforms one above the other, not including custom stages. The three suitable stages: Skyworld, Mario Bros. and Big Blue. The match must be on team stamina mode. Kirby needs to be on one team, and two other computer-controlled characters on the other team. Both teams need to have 1 stamina. Go onto the top solid platform and steal someone's power. Kirby should have somehow warped the other character to the platform below.
Walk Through Walls
Create a stage where several solid stone blocks are bunched up next to each other. Have Kirby jump right between the tiny space between the blocks. Kirby will now be inside the blocks. He can escape by flying to the top.
This glitch requires Kirby and Bowser. The battle should be a stamina battle. Bowser's health should be low, at most 30 stamina left. Allow Bowser to get a Smash Ball, and let him become Giga Bowser. Attack Giga Bowser until his HP is 0. Giga Bowser instantly returns to normal. Normal Bowser doesn't collapse. Use Kirby's inhale. If done correctly, Bowser will immediately die. This can be done with any character, but with anyone besides Kirby and King Dedede, the person needs to use a standard attack to hurt Bowser.
The Cymul enemies found in the Subspace Emissary will block any projectile that hits them, except Waddle Dees and Waddle Doos thrown by King Dedede. If a Cymul is moving and gets struck by one of these, it will take minor damage and stop moving around - this seems to indicate that it's all a glitch, as Cymuls don't permanently stop moving when hit with any other projectile.
