Princess Peach is hosting a game for everyone in the Mushroom Kingdom to play! The first person to get all 8 Power Stars from the various worlds of the Mushroom Kingdom will be granted a wish! Just make sure you get there before Bowser! A simple and silly adventure, Mariomon's story mostly focuses on the conflict from Bowser trying to get the 8 Power Stars before you. Otherwise, it's a pretty free form adventure where you're just trying to have fun in the game the Princess and Professor E. Gadd are hosting!
