Munchkin Mouse is a housemate that made his one appearance in the episode American Idol Parody Clip Show. It was said in this episode, that Munchkin Mouse had been in the show ever since the very beginning and a montage of all the moments with him was shown where he had been placed in random scenes from random episodes of the show. This, however, was obviously not canonical. He seems to be a parody on Mickey Mouse and Speedy Gonzales.
