Bandit was Bobby Hill's pet racoon. :)
In the episode to kill a ladybird, Ladybird gets lost as a result of chasing after Bandit. Bandit was thought to have contracted rabies and was going to bite Ladybird, but Bandit ran and Ladybird chased after him. Later, Bobby thought Bandit was about to bite Hank, so he took the shot, killing Bandit. Bandit was given a funeral after found out he didn't have rabies.
