Episode: "Imaginationland III” (s11e12)
Original Air Date: October 31, 2007

When terrorists destroy the wall between the good and evil sides of Imaginationland, only the most valiant and pure heroes can stand in defense of the Predator, the Minotaur, and the Woodland Christmas Critters. Among them is the famous Italian plumber Mario, without the aid of his green-clad brother, stomping goombas and other wrong-doers in the battle to save our imaginations. Just imagine if Miyamoto never imagined Mario. You can't? That's because a Mario-free world is imaginary.
