Fission City has suffered a blackout as Dr. Paradigm unveils the Wolverinepedes (a wolverine/centipede hybrid) which will be a solution to Fission City's toxic waste problems. The Street Sharks are contacted by Paxel of the G.E.C.O.s (short for Genetic Engineered Cave Organism) on behalf of Robert Bolton where they learn that toxic waste is leaking into their underground home beneath the garbage dump. The Street Sharks discover that the Wolverinepedes are a cover for Dr. Piranoid's illegal toxic waste-dumping property where the Wolverinepedes have been getting bigger from the consumption of toxic waste.
