Crustacean Crime Theater is a TV show that only appears in the episode "Life of Crime." It's a show in which Crustaceans do crimes. SpongeBob, Patrick and Mr. Krabs, were the only characters to be seen watching the show.
In the show, a mean hermit crab (possibly the Sneaky Hermit) stole a sleeping hermit crab's shell. The sleeping hermit crab wakes up and told police that a hermit crab stole his shell. The police caught him and put in jail.
