Story Mode
In Story Mode, it was the last board played. The heroes arrive in Bowser's Castle and realize they are still small. Bowser, along with Bowser Jr., pick them up and throw them in their Pinball Machine.

If the player has the most stars after 10 rounds and win, Bowser attempts to shrink them again with the Minimizer. However, Donkey Kong and Diddy Kong come at the last moment, although only coming for the free food in his party, and accidentally broke the Minimizer, which makes everyone grow back to their normal size. Bowser then tells them that he has another weapon, the Megamorph Belt. The Superstar faces Bowser in the minigame Bowser's Block Party and if they win, the player clears the whole of story mode.
