Bowser has kidnapped Peach again, but this time, Mario's hoarding tendencies are kicking in. He's grabbing all of the items in the kingdom, even when he doesn't really need them.

DaSmileKat manages to improve on the previous movie by 00:01.38 seconds through careful optimization of almost every level.
