Cushy Cloud (Creamy Cloud in Japanese) is the third level of Kirby: Squeak Squad, based on the sky and electricity. Its boss is Mecha-Kracko, which is run by Doc, a member of the Squeaks. Three scrolls can be found here.
Each stage is unlocked in succession after clearing the previous one. Defeating Mecha-Kracko is necessary to move on to Jam Jungle. For more information about a particular stage, click on the link to the stage's page in the table.
