Mickey Mouse: Disney Animated Shorts

The Shindig (1x20)

: 29, 1930

The first cartoon where Clarabelle is named on-screen, and the one where she first wears a dress - embarrassedly pulling it up to conceal her udder when she's introduced. Mickey, Minnie, Horace, and Clarabelle are off to a wild barn dance. There Mickey plays the harmonica and dances with gigantic Patricia Pig, then joins Minnie in a duet on "Pop Goes the Weasel."
