This stage is a sub-game of sorts. The Kirbys enter a Dedede-shaped building, then are whisked off to the game. Up in the clouds, the Kirbys have to contend with bubbles that come flying in, then back out. These bubbles hold Fruit, bombs, and other items. The Kirbys want to grab the fruit while avoiding the bombs. Eventually, the game ends, and the Kirbys can proceed to the stage exit.
Medal 1 - The Rainbow Medal will come down in a bubble alongside a bomb. While descending, they will switch places.
Medal 2 - A large bubble containing this medal and some fruit comes down briefly. All 10 Kirbys are needed to bust it open.
Medal 3 - One of the earlier bubbles has a Key inside. The Kirbys will need to grab onto it, and hold it until the very last bubble comes, holding a chest containing the medal.
