Mr. Muscul[citation needed][1] is a minor character who makes several cameo appearances throughout the series, first appearing in the episode "Shanghaied."


He is an olive-green fish who has a big, muscular figure with tattoos dotted all around his body. He has orange hair made into "spikes" and he wears headphones.


He is rather rude and physically aggressive, as he is not afraid to beat people up should they mess with him. Sometimes he will even exhibit violence towards others for no reason or for the entertainment of the kids.

Despite this, he is shown to have a nice side, as he happily gave Patrick a high-five and attended SpongeBob's birthday party, wishing the latter a happy birthday.
