The Turbo Undercover Fighting Force, also known as T.U.F.F., is an organization that Dudley, Kitty, Keswick, and The Chief work for in the United States that is located in the all-animal city of Petropolis, California. Most of the agents have badges to show everyone that they work at T.U.F.F.. The purpose of the organization is to protect Petropolis and possibly the world.
The design of the T.U.F.F. Headquarters building is possibly a parody of the Titans Tower, from Teen Titans, or the tower from the episode The Architect, from Generator Rex.
The agency's acronym is a pun on the word "tough".
