“My friend, you have met a terrible, terrible demise.”
Mr. Hippo is a purple 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.
Mr. Hippo's personality resembles that of a grandfatherly advice giver. His lines in Ultimate Custom Night mention that he is good friends with Orville Elephant. He has a tendency to drone on for long periods of time. He is shown at times to be philosophical as evident by his diatribes in Ultimate Custom Night. He speaks with a Boston/New York mixed accent.
