The Super Mario Galaxy Movie

Princess Rosalina, the adoptive mother of the Lumas living in the Comet Observatory, is kidnapped by Bowser Jr., who plots to drain her power to create life to fuel a universe-destroying cannon in honor of his father, Bowser, who was defeated by Mario and Luigi and shrunken by Princess Peach. Rosalina sends a Luma to the Mushroom Kingdom, where it enlists Peach and Toad for help. Mario and Luigi are called to inspect a disturbance in the desert town of Tosterena, where they meet and befriend the dinosaur Yoshi, who had hatched in Brooklyn and was pursued back to his home world after breaking a dinosaur skeleton. In Peach and Toad's absence, Mario, Luigi, and Yoshi protect the Mushroom Kingdom and attempt to rehabilitate Bowser.
