Floyd was a croc.
He first appeared during the Pearls Nuclear Crisis as an employee of Eet-a-zeeb inc, and member of Zeeba Zeeba Eata. After the discovery that the nuclear missle would destroy the Croc's house too, he volunteered to take it out to the desert and dentonate it there.
However, he was stopped at the state border crossing.The crocs then decided to just drop it from a plane. Floyd rode the bomb down, and somehow survived. The other crocs thanked him, and discoverd that the radiation had caused him to mutate and grow an extra head.
A while later, he and Burt discovered Zebra's crawlspace. They attempted to find a way into Zebra's house by crawling around underneath his house, and disguising themselves as ants.
