Oolong named Mao Mao in the Harmony Gold dub, is a shapeshifting, anthropomorphic pig that uses his abilities for his own greedy desires. He and Pu'ar went to the same shapeshifting school together, before he was expelled for stealing the teacher's panties. This is the reason he can only change his form for five minutes at a time, requiring a one-minute break. Oolong joins Goku and Bulma in the search for the Dragon Balls to eventually steal them, but abandons this plan. He does however make the first shown wish with the Dragon Balls, wishing for a girl's pair of panties. Later in the series, he is often in the company of Kame-Sennin. He is voiced by Naoki Tatsuta in Japanese, and by Alec Willows and Richard Newman in the Ocean dub. In Funimation's dubs he is voiced by Bradford Jackson, except in Dragon Ball Z Kai, where Bryan Massey voices him.
