Mr. Hippo is a supporting antagonist in Ultimate Custom Night. His goal is to kill you. Despite being a murderous animatronic bent on killing you, Mr. Hippo does not seem to hold a grudge against you. He may even apologize for your demise. Although he believes things "could only end this way" between you and he "doesn't feel too bad about it". Mr. Hippo is then reminded of a story that he will tell to you, perhaps as a way of showing there are no hard feelings. Mr. Hippo has a strong tendency.
