Crazy Horse is a teal-colored horse inmate at Petropolis Prison who is obsessed with chainsaws. During his appearance in Dog Dish, he and other inmates almost escape the prison with the help from D.O.O.M., but are stopped thanks to Kitty and Dudley. He has only speaking lines and he said, "Nope, just chainsaws." He is voiced by Daran Norris.
