My Gym Partner's a Monkey is an American animated television series that was created by Tim Cahill and Julie McNally Cahill and produced by Cartoon Network Studios. Before the television series was announced, two pilots were made. The first one was made in late 2003 and was titled simply My Gym Partner's a Monkey. In this pilot, all characters had early designs. The second pilot was made in the summer of 2004 and was titled "A Troubled Lion". In this pilot, all characters had their final designs as in the final series. Only one screenshot exists from the first pilot.
