A two-player game for the Wii. This game features both Luigi and Waluigi as the stars and Princess Daisy as the damsel in distress. Rui, who is acting as the main antagonist, is "rejected" by Daisy, which finally drove him insane, which led to Rui dragging Daisy by her hair to his castle. Waluigi attempts to stop Rui, but underestimated him because of the boy's size and, as a result, Waluigi was knocked off a cliff into the western ocean. After a week of swimming, Waluigi washes up on the Mushroom shore. Luigi, who happen to be on a vacation, asked Waluigi what happened and aftwards the two make their way to the Western Territories and, after traversing many terrains and overcoming many obstacles, Luigi and Waluigi finally come to Daxian's castle, where Rui is "hanging" with Daisy. After a long, arduos battle the two defeat Rui, and he surrenders Daisy and runs away crying...
