When Sunny finds a weird-looking pod hanging from a branch, Uncle Balzac de Chameleon explains it's a pupa--a sort of "sleeping bag" where a caterpillar becomes a butterfly in a big change called "metamorphosis." Curiosity leads Sunny and Bobby on an exploration of other big-change artists, such as frogs, mosquitoes, dragonflies, and more.
