Audio problem: When Kup and Hot Rod are smashing up the Sharkticons, Kup says something, (I think it's after he rips the tail off one of them), his mouth doesn't match what he says.
Audio problem: When Warren T. Rat calls open season on Fievel, the cats all scramble at once to capture him. In one shot where Fievel is running from either end of the piano, he jumps upon the same key twice. The notes play, but the key never goes down at all. (00:51:55)
