|Jack M. Crazyfish|
|First Appearence:||Blackened Sponge|
|Voiced by:||Greg Baldwin|
Jack M. Crazyfish is a big fish that appears in the episode: Blackened Sponge. He is a fish in SpongeBob's dreams, but is actually a real person who lives in Bikini Bottom. SpongeBob gets a black eye from a wrench being stuck in his eye, but makes up a story that he got it from fighting Crazyfish. Crazyfish then comes to the Krusty Krab because he has heard that SpongeBob makes great Krabby Patties, and he is hungry for one. When SpongeBob spills his meal on him, though, he gets angry at him. They played Rock-Paper-Scissors, but Crazyfish cheated.
Jack is a fish with a very big body and a small head. He wears a brown suit and a yellow shirt. He has a big mustache and a small top hat on his head. His skin is lavender.
- It seems that Jack is Italian because of his mustache and clothes, which means that his name would be "Giaccamo" (Jack - a - mo).
- His voice is different on his first appearance Blackened Sponge from his second appearance 20,000 Patties Under the Sea.
- Ever since his first appearance in Blackened Sponge, he became a cameo character.
- When he walks into the Krusty Krab, SpongeBob says "He's real". Although when SpongeBob tells Sandy about him, She seems to know about him. One possible reason is that she may have met Crazyfish.
