Mickey is preparing to conduct an opera when he chases Pluto away. Pluto crashes into a magician's props backstage and spars with the hat, its rabbits, and its doves. The opera begins: Clarabelle plays flute, Clara and Donald are the leads in Romeo and Juliet. Pluto follows the magic hat onstage, to Mickey's growing annoyance. The hat falls into a tuba, and soon the animals are filling the stage.
Unfortunately the movie Mickey's Grand Opera is not yet available on Disney Plus.
