Our heroes think they are going to a benefit Spaghetti Dinner at the Linguini Empire Colosseum, but it's all a plot by the evil Emperor Augustus Septemberus Octoberus Koopa to feed the Marios to the lions.

When the evil Koopa Claus (Bah Humkoop!) tries to stop Christmas, the Marios come to Santa's rescue and Toad learns the true spirit of giving.

Mario and Luigi come to El Desertland's rescue against the evil Capitan El Koopa by donning black masks and capes to become the legendary heros "Zero" and "Zero Plus One".

Our heroes have come to Winterland so the Princess can visit her grandmother, but Koopa sees her crossing the forest all alone and plays big bad wolf.
