Johann Mouse

In the home of the celebrated Viennese composer Johann Strauss, a resident mouse named Johann Mouse makes his presence felt. Whenever Strauss plays his waltzes, the mouse cannot help but dance to the music. One day, while Strauss is away, the house cat takes to playing his master's tunes on the piano. Word spreads about a piano-playing cat and a dancing mouse, and they are summoned to perform for the emperor.
