Mario and his friends pursue Bowser to a skyscraper, where he is defeated when Mario bangs on a huge switch, causing him to be thrown into the sky. Later, Mario and his friends arrive at Bowser's castle, where they engage in a final battle against «Meowser», a cat-like Bowser. Later, after rescuing the final Sprixie, Mario and his friends are encountered by Bowser, who re-captures all seven Sprixies, and retreats to his official castle. They then find themselves in where is known as «The Sprixie Kingdom», and Mario and his friends set off to find the Sprixies. Just then, Bowser arrives and captures the Sprixie before escaping through the pipe, prompting Mario and his friends to enter the pipe in order to pursue him.
After Mario and Luigi fix the pipe in no time, Sprixie, a curious green fairy-like creature, jumps out the pipe and tells Mario and his friends the bad news. The game begins with Mario, Luigi, Princess Peach, and Toad exploring the Mushroom Kingdom, where they came across a clear pipe that is tilted.
