During a picnic out in the Mushroom Kingdom hills, Mario, Luigi, Peach and Toad see a meteorite entering the atmosphere and watch it crash nearby. When they go to investigate, they discover that it is not a meteorite, but actually a spaceship that has been too badly damaged to retain flight. They enter it and come across the pilot, a alien named Cosmai, who tells them that her home planet has been taken over by the evil Nukteks.
