It's Sunny Starscout's first time hosting a sleepover for her best friends, but she has a "wee" little problem that she'd rather keep a secret. When she's caught out, it seems like it might be the end of the world. Fortunately, Zipp Storm is the big-sister type, and offers to help take care of everything.

Contains: casual diapering and references to bedwetting.

Nothing mature at all here, folks.
