1937 Mickey Mouse short directed by Ben Sharpsteen

The demons of hell play music for Satan, whose delight turns to wrath when an insubordinate refuses to become food for Cerberus.

Mickey has been reading Alice in Wonderland, and falls asleep. He finds himself on the other side of the mirror, where the furniture is alive.

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.
