Stars are a recurring motif throughout the Kirby series, especially the yellow five-pointed star. They represent Kirby himself, since the Japanese titles for the Kirby's Dream Land trilogy and Kirby: Right Back at Ya! are simply Hoshi no Kābī, literally translating to "Kirby of the Stars." Against Nova in Kirby Super Star and its remake, Kirby's Starship is formed from stars themselves.
Stars are a common decoration on most things related to Kirby and objects common in the series, for example, Kirby's Warp Star, Pop Star, King Dedede's Hammer, and Star Blocks, and they have a prominent role in gameplay.
Stars are collectibles introduced in Kirby's Dream Land 2. Whenever Kirby has collected enough, he gets a 1UP. Every time Kirby collects one, a gauge at the bottom of the screen fills up. It takes a varying number of stars before Kirby is granted the 1UP. Getting large numbers of them are possible in the Goal games of Kirby 64: The Crystal Shards and Kirby: Canvas Curse, so the numbers are scaled up.

In Kirby's Dream Land 3, stars are collected in pieces, and since each piece is worth 1/5th of a star, essentially Kirby needs to find 30 individual pieces before being granted a 1UP.
In Kirby 64: The Crystal Shards, stars come in several different denominations: Yellow stars are worth one point, red ones are worth three, green ones five, and blue ones ten. Blue ones are only found in place of Crystal Shards already found when repeating a previously-cleared level. When facing a boss, the star gauge is replaced by a health gauge representing the boss's health, and becomes red instead of yellow.
Upon performing the inhale, Kirby has a choice to either swallow the object in his mouth or spit it back out i.e. the Star Spit attack. Should he decide to spit it out, the object, regardless of what it was, becomes a star projectile. If Kirby inhaled more than one object at once, the resulting star is much more powerful, and can go through enemies and hit larger ones more than once. In Kirby: Squeak Squad, such stars can be manually made using Bubble on ability-neutral enemies and combining the bubbles within the Copy Palette.
Star projectiles in Kirby 64: The Crystal Shards have a different appearance to the five-pointed yellow variety in every other game. Instead of spitting objects out as stars, Kirby spits out the object as it is. When lifted above Kirby's head, however, if it is an ability-yielding enemy that has been swallowed or any multiple enemies that have been inhaled, they turn into stars; the ones which yield copy abilities turn into 4-pointed stars with the color of the ability and a ring surrounding it, while ability-neutral ones give white, 5-pointed stars. If two enemies are inhaled simultaneously and one is ability-neutral and one is not, the resultant star has a light texture of the color representing the copy ability. If two ability-yielding enemies are swallowed at the same time, the star will have the color of the Copy Ability, eight points, and two rings around it.
Should Kirby be using a copy ability and take (enough) damage, the ability will be lost in the form of the ability star. This star is very fragile and does not survive very long outside of Kirby, and bounces about the stage, but can be re-inhaled if Kirby gets to it in time. Should it be lost in water, it will float slowly upwards towards the surface. It disappears as soon as it touches Spikes or Lava. In Kirby 64: The Crystal Shards, Kirby can hold an Ability Star above his head, and can either throw it at another enemy to mix abilities, swallow it, or just dispose of it. In Kirby's Return to Dream Land, ability stars have their own unique coloration, and a symbol on the front. There are even ability stars for Super Abilities.
Blue Stars are items exclusive to Kirby Tilt 'n' Tumble. They look like the Sparkling Stars from Kirby's Dream Land, but are blue. One Blue Star is hidden in each level of the game. If Kirby gets a Blue Star and beats the level he found it in without losing a life, he will leave the level on a Bonus Star, which is a blue version of the Warp Star. From there, the player must choose a sub-game to play.
Red Stars are also items exclusive to Kirby Tilt 'n' Tumble. They look exactly like Blue Stars, but are red in color. One Red Star is hidden in each level of the game. Like with Blue Stars, the player does not get any benefit from them unless he/she beats the level without losing a life. To complete the game 100%, the player must collect all of these.
