Jimmy the Cockroach

Jimmy the Cockroach is Reuben's pet insect seen in Lilo & Stitch: The Series. He only appears in the episode "Checkers". When Gantu notices Jimmy, he makes a vain attempt to kill the bug, much to Reuben's horror. Later, when Gantu steals Experiment 029 (Checkers) and takes over as king, Reuben and Stitch rally an army of other experiments to rebel against Gantu. Reuben even uses Jimmy to help out, and Gantu is successfully overthrown. At the end of the episode, Reuben is seen congratulating Jimmy on Gantu's ship, while Gantu is given the punitive duty of cleaning the bathroom under Hämsterviel's orders.
