Continuity mistake: After Fievel gets captured by Warren T. Rat, he's ordered to work alongside numerous other mice in a tailor shop. In the following scene where everybody's asleep, Fievel jumps from his bed and walks over to the nearest window - making a reference to Rapunzel's hair and how well it would work to escape with.
