Mousse

A boy blindly following his love, Shampoo, who detests him. Even with his thick bottle-lens glasses, he mistakes statues, telephone poles, and bystanders for other people.

He shows up in Japan looking for Shampoo, even though he always fails to defeat her in a fight, but Cologne tells him Shampoo is going to marry Ranma. So he challenges this new rival for Shampoo's affections to a man-to-man fight (a troublesome point for Ranma).

When Ranma defeats him, he returns to China and seeks training at Jusenkyou, where he walks into Yaazuniichuan, a spring where a wild duckling drowned 1300 years ago (if there's anywhere in the world a duck could drown, it's there). He returns to Japan with a supply of Yaazuniichuan water to turn Ranma into a duck, too, but (of course) fails.

Moose hates Ranma, and would dearly like to do away with Shampoo's "husband".
