Fish is a rock band that SpongeBong and Hashbrick like. They seem to be a favorite for stoners, as people who go to Fish concerts take and use sea-mushrooms to visualize that their music rocks. They were introduced in Crystal Meth. In the same episode, SpongeBong, Hashbrick, Spliffward, and Crystal attended a concert. Crystal was freaked out when she saw SpongeBong, Hashbrick, Spliffward, and Fish all in real-life forms.
- Though Fish does appear, they are only seen in cartoonish form during the news report at the beginning of the episode. At the concert, they are only seen in the real-life forms by Crystal.
