Mario and Luigi, along with DK and Cranky Kong, find their way into the Mushroom World, where they find the Mushroom Kingdom. They find out that an evil villain named Bowser (the same villain who vandalized Mario and Luigi's world) has seized the Power Star to trap the citizen's of the Mushroom Kingdom inside the castle walls as holograms, and has captured the land's king. Teamed with two explorer Toads and the princess of a foreign desert country, the trapped Princess Peach sends the team of heroes on a grand mission to defeat Bowser, retrieve the star, and restore the Mushroom Kingdom to its former glory.
