After talking with the chancellor, he meets Mallow, apparently a frog from Tadpole Pond. Mario and Toad then travel to Mushroom Kingdom to inform the Chancellor of the Princess's kidnapping. Exor destroys the bridge and Mario narrowly escapes. However, when he arrives he is unable to enter the castle and Exor, the giant sword, tells Mario that the keep is now the property of the Smithy Gang, taken over to help with its quest to take over the world. Mario has no idea where she or Bowser are, but goes to check the castle. When Toad discovers that the princess is not there, he asks Mario to go back to Bowser's keep to bring her back. Mario ends up landing back at his house where Toad has been searching for Toadstool. Mario views the damage done to Bowser's Keep by Exor. The crash sends Mario, Toadstool, and Bowser flying in separate directions. A giant sword named Exor falls from the sky and crashes into Bowser's keep, destroying the Star Road on the way.

Upon defeating Bowser and rescuing the princess, however, the castle begins to shake. After going through the castle, Mario finally catches up with Bowser, and proceeds to battle him on the chandeliers. He chases Toadstool and Bowser and ends up at Bowser's Keep. Mario exits his house then and sees Princess Toadstool in peril. Suddenly, she is kidnapped by King Bowser using the Koopa Clown Car. Princess Toadstool sits peacefully on a hill outside Mario's Pad. The following section is transcribed from the Super Mario Wiki. This was the first (and only) game done by write-in request, the fans wanted it, so I did it to celebrate it hitting Wii Virtual Console in September 2008.
