Ranma ½, part 3 number 4

Shampoo chases Ranma, then Cologne joins. After that Mousee, another fighter without honor, makes his appearance. Without his glasses on he's almost blind and is constantly mistaking one person for another, including hugging Ranma thinking he's Shampoo. He and Shampoo are childhood friends, but for some reason Mousse has gotten it into his head that he and Shampoo are going to get married.

Cologne shows up and says Ranma is Shampoo's finacee so now Mousse joins the group who hate Ranma, even though Ranma doesn't want Shampoo as a wife. Ranma and Mousee plan to fight.

That night when Ranma-chan plans to take a bath, though, she pours cleansing water over her head and says it's too hot, although Kasumi thinks it's barely warm. Cologne shows up and says she's caused Ranma to develop a condition where water will appear to Ranma will not be able to change out of the girl form he is currently in.

Ranma is supposed to have a man-to-man fight with Mousse, but he can't change back into his boy form. He shows up as Ranma-chan in disguise as a magician. After fighting for a bit she doffs the disguise and appears as Ranma-chan.

The problem is that Ranma-chan is much shorter than Ranma so her arms and legs are shorter and it's harder for her to fight the taller Mousse.

As they fight more and more of her body is exposed as her outfit is shredded by Mousse.
