From WiKirby, your independent source of Kirby knowledge.
Ability Planet is an extra auxiliary stage which can be found in Far-Flung Starlight Heroes in Kirby Star Allies. To unlock this stage, the Story Mode must be completed. This is not an official stage, as it does not have any Picture Pieces to collect, and it cannot be 'cleared'. It is mainly meant to serve as a reward for Kirby by providing every Copy Ability (and potential friend) in the game, but it also has a special challenge room, unlike previous Copy Ability Testing Areas.
This stage consists of only two areas. The first is the one which Kirby will find himself in when he enters the stage. It is a large room with decks featuring every Copy Essence in the game. To the sides, there are rooms with certain enemies inside them, and hazards which those enemies (once made friends) can help to clear, though doing so only yields minor rewards, and is largely meant as a demonstration. At the top of this room, there are four enemies which provide the limited-use abilities that don't have corresponding friends, as well as a door to the other area.
The second area is a square room with a few decks on each side. This room is one long ambush, and if Kirby stays here, he will have to fight a great many enemies. He can leave at any time, however, by accessing the door up top. Should he stay and survive long enough to defeat all the enemies, he will be rewarded with a huge cache of treasure chests.
