The Flying Mouse is a fan favorite, though I’d venture to guess that it’s for the great character animation and catchy themes than the story. In short, it’s about a mouse who wants to fly, is given wings by a magical fairy, and is shunned by his family, the birds he wanted to emulate, and the bats (who have the best song in the short). Eventually, the fairy restores him to his wingless, original self with the admonishment “Do your best. Be yourself.” The human form that the fairy takes is another example of a proto-Snow White (or perhaps the Pinocchio’s Blue Fairy), and the bats and spider hearken back to the characters in the first few years of the Silly Symphony series.
