Little Jay has special instructions to give their pet, Pupcake, a bath! Pupcake is mischievous and doesn't quite pay attention to instructions though. Splashing Jay, thinking it's playtime, Pupcake eventually gets Jay into the bath as well! Jay is concerned that their diaper is going to get soggy, and squishes and plays with it while Pupcake watches curiously. Soon the diaper explodes in the water! So much for puppy bath time!
