This show was a spin-off to the sequel of "An American Tail" which was "An American Tail: Fievel Goes West". This is basically a series of events that take place after "An American Tail: Fievel Goes West". Cat R. Waul and T. R Chula are at it again. They are always trying to eat the mice, as they try to do in the movie, but Fievel, of course, slips in and stops them. With the help of his friend, Tiger, he survives his encounters with Cat R. Waul, sending them out with their evil plans foiled! This all takes place where the movie takes place, in Green River.
