Tom Cat goes hunting, leaving Mickey and the mice to play in his absence. Mickey and Minnie dance on the piano while other mice create a makeshift orchestra using various objects. A parrot tries to join in, but his bad singing causes him to fall into a spittoon. Later, Mickey uses a mousetrap to launch himself to a wheel of Swiss cheese, but instead of eating it, he uses it to create music on a player piano. The mice then form a phonograph to play more music, bringing joy to all.
