Hoppopotamus is half rabbit, half hippopotamus. She is called Hoppo by her friends. She is a Wuzzle who is a hippopotamus with a rabbit's ears, buck teeth and a fluffy tail. She has blue fur with a purple tummy, and she loves to sing and act. She is a pushy demanding diva, but she can be sweet. However, when toughness is called for (particularly in dealing with the regular villain, Crock), she is the toughest Wuzzle of all. She has a crush on Bumblelion, but he has his heart set on Butterbear.
