The male hippo is a minor character in The Backyardigans.
In the "What's Bugging You?" episode, an adult male hippopotamus can be seen in a photograph. The picture is located in Lady Tasha's house, meaning that he could be one of Tasha's relatives or ancestors.
The hippo is mostly a yellow color. He wears a brown cardigan, a collared white shirt, an olive green vest, and a brown bow tie. He also wears a brown top hat.
The hippo has appeared in one episode of The Backyardigans: "What's Bugging You?" from season three.
