Crazy Keith

An illegal immigrant Koala from Brisbane who lives under the floor boards of Barney's flat with his inanimate girlfriend Doris, of whom he ironically involves himself in conversation with on a regular basis. He is Nev's best friend, but often ropes him into hare-brained schemes, usually with the intention of stealing Mr Prank's secret ice cream stash. His existence is unknown to all the characters except Nev, Beatrice and Barney. As shown in Curse Of The Were-bear he is part were-bear. He can speak a prehistoric language as shown in Cave-bear and he has not had a bath for years. He mentioned 3 times that koalas are an endangered species and he's very greedy. He adores Ice-Cream and pizza and often over-eats, meaning he becomes so fat he gets stuck. He has a brother called Dennis and an uncle called Bruce. In the episode Crazy Keith - Extreme Koala he was a surfing superstar back in Bondi Beach and that's when he met Doris. He often discovers the important things during the series [like that Dev is a criminal in Cousin Dev] and he often mistakes things for other things [like the song that revives the dead mummy in Yummy Mummy is an ancient Egyptian comedy folk song.
