Johann Mouse (1953)

In the residence of Viennese composer Johann Strauss, there was a lively mouse named Johann. He couldn't help but dance whenever Strauss played his enchanting waltzes. One day, while Strauss was out, the house cat decided to take a turn at the piano. The news of a cat playing the piano and a mouse dancing spread quickly, leading to a royal summons for them to perform for the emperor.
