Rex is a pet worm that SpongeBob took in after Gary left him in the episode "Dumped." Ironically, Rex left on the bus after SpongeBob was saying worms are "So loyal, so trusting, always by my side!" Rex has only appeared in that episode.
- Rex looks a bit like Jan and Mr. Doodles, but he has a color shade of light teal.
- Similar worms have appeared in other episodes, most recently "Plankton's Pet."
