Mario, Luigi, Peach, and Toad were at Peach's Castle for a feast. When suddenly, there was a rumble. Bowser's airship broke the roof of the castle! (and of course the dining room is on the top floor! How stupidly built). Bowser gets away with Peach and now The Mario Bros and Toad must save her. Bowser takes her to his castle, and puts her in a cage, which, like always, the bros must defeat bowser to unlock the cage to get her.
