The Sparkling Stars, also known as the Twinkle Stars, are magical items that are collected at the end of each level in Kirby's Dream Land. There are five of them in total - one held by each Boss - and collecting all of them allows Kirby to inflate to immense proportions.
Kirby's Dream Land
In Kirby's debut title, King Dedede and his goons come down to Dream Land from Mt. Dedede and steal the Sparkling Stars from the sky - robbing its denizens of their power source - as well as all of their food. Without them, the Dream Landers are unable to collect more food, and begin to starve, prompting Kirby to go and get them back.
At the end of each level, Kirby battles a Boss, who drops one of the stars upon defeat. After besting King Dedede, Kirby is able to collect the last one, and he uses them to turn himself into a giant hot air balloon, and carry Dedede's castle - along with the food inside - back to Dream Land. From there, it can be presumed that the stars were returned to their rightful position.
Kirby's Block Ball
Once again, King Dedede stole the 5 Sparkling Stars and hid them in his castle. After defeating King Dedede, Kirby collects the Sparkling Stars and uses them to break the castle down to uncover the fountain that it had been built over.
Kirby Super Star / Kirby Super Star Ultra
Kirby collects four of the sparkling stars in Spring Breeze, which serve the same function that they did in Kirby's Dream Land.
The stars that Kirby collects in Milky Way Wishes are reminiscent of the Sparkling Stars, though it is not clear if they are the same objects or not.
In Revenge of the King, Kirby collects three Sparkling Stars from the bosses in the first three stages. When he faces off against Kabula in Mt. Dedede Sky, she shoots down his Warp Star. At this point, the three stars Kirby collected coalesce into a Starship, which Kirby can then use to battle the menacing blimp.
Kirby Tilt 'n' Tumble
Much like in Kirby's Dream Land, the goal in this adventure is to retrieve the Sparkling Stars, which King Dedede has once again stolen. This time, there are 8 to collect, one from each area.
Kirby's Blowout Blast
A Sparkling Star makes an appearance after King Dedede is defeated. It flies down toward where he landed, and causes him to grow giant, then start attacking Kirby again. The star's effect wears off when Dedede is defeated again.
- The Sparkling Stars' use in Kirby's Blowout Blast makes it similar to the Grand Stars from Super Mario Galaxy 2, as both cause the villains who use them to grow giant.
