Ranma is determined to infiltrate the Furinkan High girl's locker room when he gets a map from Ryoga that shows there's a old spring beneath it that can cure his curse. It proves harder than Ranma thought though, since the girls are on high alert due to the recent raids by Happosai.

It's cookie baking time in the home ed. class, and Akane and Kodachi both want Ranma to taste. Not taking no for an answer, the Black Rose falls back on blackmail, causing Akane to become even more determined to get Ranma to eat hers.
