Prism Plains is the first level in Kirby: Squeak Squad. It has a theme of grass, a common theme in beginner levels in many video games. One Ability Scroll is available in this level, in Stage 3. The boss of this level is King Dedede. When Kirby defeats Dedede for the first time, he is instantly taken to the first stage of Nature Notch, which is the next level.
Each stage is unlocked in succession after clearing the previous one. Defeating King Dedede is necessary to move on to Nature Notch. For more information about a particular stage, click on the link to the stage's page in the table.
