Plot
After traveling through the lands of Mario's Star Quest, Mario receives a letter from Princess Peach telling him to come to her castle. Mario goes to the castle to find out that Bowser has stolen the Eternity Star, the star that holds an extreme amount of power that secures life for every single creature, as long as it's not on evil hands, which is not the case in this situation, as Bowser uses its power to become Dark Bowser and conquer the universe. To save the Eternity Star, Mario travels with Peach to Bowser's new castle, The Dark Castle. Once arriving in the Dark Castle, Mario finds many warp pipes to different worlds, containing stolen stars from the Mushroom Kingdom. Mario has to go to all these worlds and get enough stars to face Dark Bowser in his own world, The Dark World, only then to see his extreme form. Will he be able to save the universe from this cosmic disaster?
