The clock strikes midnight, the bats fly from the belfry, a dog howls at the full moon, and two black cats fight in the cemetery: a perfect time for four skeletons to come out and dance a bit.

Mickey Mouse is working as a hot dog vendor at a carnival when he meets and quickly falls for Minnie the "Shimmy Dancer". That night, Mickey and a pair of alley cats serenade her by performing the song "Sweet Adeline", much to the dismay of Kat Nipp, who is trying to sleep. The short marks Mickey's first speaking appearance.

Parody short about Leon Schlesinger and his company.
