Oolong (ウーロン) is an anthropomorphic, shapeshifting pig who makes some minor appearances in Dragon Ball Z Abridged. Just like in the anime series, he's shown to be slightly perverted (not as much as Master Roshi) and has a hobby of collecting panties (particularly Bulma's). He's also shown to ignored by everyone else due the the fact that no one celebrated his birthday, which was a week before Turtle's, in "There's Something About Maron". At one point, he was against Master Roshi's idea of buying a submarine fearing that he will name it after his junk (which he eventually does).
Goku doesn't really considering him as his friend but more as his emergency food along with Icarus.
There is a running gag were when he asks what is in his food (it usually contains pork) followed by him enjoying the fact it is pork. Strangly he didn't mind eating ramen (which had pork) in the original DBZ episode which Chiaotzu made.
