Hippo wants a girlfriend. He has a crush on a young hippo starlette named Jessica who lives in Mozambique. She was found as a newborn washed up on the banks of a river. She is now pampered by humans and plays with dog friends.
Hippo is also pampered by humans and has both a dog and a cat as friends, so they already have a lot in common. He's pretty sure she'll fall for him if he wears a sombrero.
