A Giant Rat appeared in NYC, so Zilla Junior and H.E.A.T. move in to try to capture it. Three redneck hunters appear and complicate matter though, as well as getting more than they bargained for when dozens of giant rats come from the bowels of the city. They finally call in the military, but are unable to get out of the tunnels before they get bombed. Zilla floods the rats' tunnels, and a team headed by Animal Palotti and Audrey Timmonds rescues H.E.A.T. from the tunnels. One of the largest rats survived, and was taken to the Aliens base of operations in the Pacific ocean. It was present during the launch of the invasion, but didn't take part, and disappeared after the ensuing events.
