One day, while visiting Mario, Princess Toadstool was picking flowers in the garden...
Suddenly, out of nowhere, Bowser appeared and grabbed the Princess again! (Like you'd expect anyone else to?) Mario, hearing Toadstool's scream for help, sped off alone toward Bowser's Keep. After Mario trounced Bowser for the millionth time (this time they fought on one of Bowser's chandeliers), everyone felt Bowser's Keep beginning to shake!
A HUGE sword crashed into Bowser's Keep! What's gonna happen now?
