In the film, he lives with J.W. and he needs a partner, he certainly tells J.W. what animal it would be, but Irving pushes a cage with Clown-O's pet bear, Mr. Frisky. Clown-O thinks Mr. Frisky is pretty dangerous (although Mr. Frisky acts like a good dog). He touches him and Mr. Frisky got him and he runs away in a chase of Mr. Frisky. He is not seen again for the rest of the film, but it is possible that he runs back to his house.
He has a white head, red lips, red nose, yellow clothing, red shoes, green hair, white collar, and a purple hat with a yellow flower.
