Mad Mod then rigs a contest so that he and Orochimaru's group can deliver the deadly pizzas to the Mobians. However, due to heavy customer demands the Mobians end up getting ordinary pizzas, and the booby-trapped pizzas are out somewhere in New York. Orochimaru's group and Mad Mod may have ended up becoming victims of their own plots when the Killer Pizzas do not discriminate between ally and enemy.

Plot: Orochimaru's group is running low on Mutagen, so Redcap's group sends a canister that ends up in the Everglades due to transdimensional problems. Orochimaru's group sees the Mutagen canister broke en route, but did create five mutant weasels whom they befriend and get to commit robberies, as well as to hate the Mobians, despite the lead weasel, Smart Guy's, suspicions. Tails, Silver, and Omega also realizes Orochimaru's group is ordering robberies of chemicals in order to mass produce Mutagen. The Mobians and their allies must not only face the misguided mutants, but their job is complicated due to the NYPD now having an Anti-Mobian task force.
