Mario and Luigi come to the new Coconut Mall after the 7-Year remodel. At the Grand Re-Opening Bowser is tearing it down to build Koopa Troopa Stadium, a battling arena that he plans to use to defeat Mario. The Luma that Mario used for his Space adventures in Super Mario Galaxy comes to Mario and enters him once more. Rosalina comes to Mario and explains that he can use the Star Karma to restore parts of the Mall. All he has to do is collect it at the parts of the mall. She repairs the mall temporarily and leaves. With that in mind, Mario and Co. set off on a new Mario Party: the Coconut Mall Party!
