Egon is testing some machines on Slimer to try to make him itch, but it makes him laugh instead. Ray is nearby and the two of them discuss the experiment, while Peter is weightlifting to try and gain muscles so he can show off on the beach. When he adds too many weights, he's flung through the air, lands on Egon's machine, and is hit by a beam and knocked unconscious.
He wakes up in bed, glowing, and then he becomes very buff. When Ray and Slimer load some ghost traps into Ecto-1, Peter discovers that he's also become able to fly (though he lands clumsily). Then, they're called to a museum, but Peter flies instead of riding in the Ecto-1. The Ghostbusters are hesitant to shoot at the ghost because it's near some statues they don't want to break, so Peter grabs the ghost and throws it right into the trap.
This makes him famous, and people start calling him "Venk-Man" so he starts calling himself that. He basks in the glory to the ire of Winston, and even starts wearing a super suit. Egon determines the powers are temporary, so he assigns Slimer (who also wears a costume and goes by Super Spud) as Peter's sidekick to make sure he doesn't hurt himself when the powers go away.
The Ghostbusters are called to a zoo to deal with a giant rat ghost, which Peter beats up. Winston is still annoyed at Peter being a superhero, while Janine is annoyed at people phoning just to talk to "Venk-Man". Egon reveals that the device which gave Peter the powers is broken, meaning that the powers could go away at any moment. He reveals he tried to warn Peter, but Peter was too cocky to take it seriously.
Peter and Slimer, meanwhile, are trying to take on a ghost in the ironworks alone. Peter starts fighting the ghost, but his powers taper off. He's about to fall into a vat, and Slimer struggles to hold him back. Luckily, Winston and Ray show up, save the two, and trap the ghost. At home, Peter apologises for being rude, and they discuss ordering Peter and Slimer a pizza each.
