Help! I'm a Fish
A Great White Shark and pilot fish accidentally drink part of the antidote. This gives them human intelligence. The pilot fish names himself Joe and creates a civilization of talking fish with himself as the leader. After Fly tries to steal the antidote from him, Joe has Fly, Chuck and Stella locked up but they escape. They find what they need to create the antidote but Joe steals it from them after his shark wounds Fly. Chuck then takes Fly and Stella to McKrill’s pipes to flood his laboratory and take the antidote. Joe follows them and steals it to make himself smarter. Fly calls Joe stupid. When Joe tells Fly that he can kill him, Fly tells him that any idiot can do that. He asks Joe many trivia questions about mathematics, special relativity and philosophy. When Joe does not know the answers, he drinks the antidote to figure them out. He drinks enough of the antidote that he becomes human and drowns. Fly, Chuck and Stella get the antidote and become human again. Chuck thinks Fly is dead but it turns out he is alive and just has a broken leg. Chuck learns to swim and Fly starts being interested in computers and science. Stella gets  a seahorse, Sasha, as a pet.
