Lord Bowser returns in Mario's next big adventure. Bowser and the seven Koopalings have taken over the rest of the Mushroom World, transformed the kings of each Kingdom and captured Princess Peach again.

Mario and Luigi must take down Bowser's army and reverse the curse placed on each of the seven kings and save the princess using an array of all new power-ups such as the Super Leaf, transforming Mario into the flying Raccoon Mario.
