An ox who debuted in numerous "Phony Bologna" advertisements for the Oxymoron company. He also makes cameos in some episodes. His name is a parody of oxymoron, a phrase in which an adjective that means the opposite of the noun that it describes is used (e.g. a smart idiot, a planned coincidence, Hopeless Optimistic, etc.), as well as the cleaning solvent Oxyclean, whose ads are pitched in a similar style.
He is seen in an advertisement for Oxymoron Inc. that is in front of the Megaville Center for the Arts.
