From the introduction: Welcome, Jumper, to the Mushroom Kingdom! You’re just in time for something really special. In just a few days from when you arrive, Princess Peach will be hosting an Origami Festival in Toad Town, right outside the castle. But, all is not well. Unbeknownst to the Princess, the Origami Craftsman has used a forbidden technique that allows origami to come to life! It’ll be up to Mario and his pals to stop the rampaging Origami King before the whole world gets folded up!
