This is the page about Jack M. Crazyfish. For other uses, see Jack (disambiguation).

Jack M. Crazyfish[1] is a character who is the "main villain" of the episode "Blackened Sponge." He is a fish in SpongeBob's dreams, but he is actually real, and lives in Bikini Bottom.


Jack is a lavender male fish with a very big body. He wears a brown suit and a yellow shirt underneath. He has a big mustache and a small green top hat on his head. On the side of his head are three magenta spots.


"Blackened Sponge"

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 Crazyfish. Crazyfish then comes to the Krusty Krab because he heard that SpongeBob makes great Krabby Patties, and he's hungry for one.

"20,000 Patties Under the Sea"

He makes a cameo throwing rocks at Plankton.


  • His voice is different in his first appearance ("Blackened Sponge") from his second appearance ("20,000 Patties Under the Sea").
  • When he walks into the Krusty Krab, SpongeBob says "He's real." However, when SpongeBob tells Sandy about Crazyfish, she seems to know about him, possibly because she may have seen or met him.
  • He was voiced by Greg Baldwin in his first debut, who also voiced Mysterio in 2008 video games Spider-Man: Web of Shadows.
