Mario has been around Princess Peach for years, so it only make sense that he'd marry him. But stepping in his way is Bowser once again trying to marry Peach just like in the first movie, but in this one, Bowser might actually succeed in having Peach fall in love with him. Mario is kicked out into a small quiet ghost town where he befriends a hat ghost called Cappy, who with incredible powers can possess other creatures using Mario's hat. The two band together to travel to every kingdom, collect the power moons, and stop the wedding!
