|“||After I defeat the last boss of each stage, they will leave behind one of the special Sparkling Stars that King Dedede has stolen. When you see it, make sure you grab it so that you can return it to the people of Dream Land.”|
|— Instruction manual description • Kirby's Dream Land|
According to the instruction manual, the Dream Landers use the Sparkling Stars to "play and work," and without them, they become "unable to gather food." King Dedede steals all five of them and gives them to his strongest henchmen to guard, keeping one for himself. Every stage in the game has one Sparkling Star that is obtained after defeating a boss.
After Kirby collects the last Sparkling Star, they all gather in his body--causing Kirby to blow up to a huge balloon-like size and carry King Dedede's Castle (full of Dream Land's stolen food) back to the Dream Landers. After a bit, he returns to normal; the Sparkling Stars leave his body, but start floating beneath the castle, suspending it in the air while the food pours out of it.
King Dedede steals the five Sparkling Stars and hides them inside his castle in Blockworld. At the end of the game, Kirby defeats the villain. The Sparkling Stars destroy Dedede's stronghold and reveal that a fountain is built on its foundation. Kirby dances in the fountain's gushes as the credits role.
In Spring Breeze, the same basic premise as Kirby's Dream Land occurs again, as it is based on the original formula as a tutorial sub-game. This time, King Dedede steals only four of them. In the remake-exclusive Revenge of the King, Dedede steals three of the stars once again to lure Kirby into a revenge plot. When the new and improved Kabula destroys Kirby's Warp Star, the three Sparkling Stars he has collected merge into the Starship, allowing Kirby to return and defeat Kabula.
In Level 5, after Kirby defeats King Dedede and knocks him off the tower, a single Sparkling Star descends from the sky. It increases the king's size, turning him into Giant King Dedede. This also happens in Level 5 EX and the Secret Path, turning him into Giant King Dedede's Revenge and Giant Masked Dedede, respectively.
- Sparkling Stars are called Twinkle Stars on Club Nintendo's site.
- Kirby's Blowout Blast is the only game to feature a Sparkling Star in which it is not stolen.
