Role in series
SpongeBob gets a black eye from trying to take the lid off his toothpaste, but he punches himself in the eyeball and makes up a story that he got the black eye from fighting Jack M. Crazyfish. Jack then comes to the Krusty Krab because he heard that SpongeBob makes great Krabby Patties, and he is hungry for one.
He makes a cameo throwing rocks at Plankton.
- His voice is different in his first appearance from his second appearance.
- Jack M. Crazyfish's existence is first hinted by Sandy when she reacts to his name in shock, which implies that she may have met him at some point in the show.
