Mr. Hippo is a purple pygmy hippopotamus animatronic with lavender accents around his muzzle, belly, and eye sockets. He was modeled after the original animatronics from the first game. He has blue eyes, four teeth from the bottom jaw, and a black top hat. On his chest is a flower with red petals and a yellow center, and there are two black buttons below that.

He has an electricity power source box which has circuits and wires to activate him just like the other mid-size animatronics.
