The newest chapter of the Paper Mario story isn't just out of this world ... it's out of this dimension. What at first glance appears to be a 2-D side-scroller ripped straight from the stylized pages of the Paper Mario universe soon turns into a hilarious dimension-shifting platformer possible only on Wii.
Mario and Luigi are enjoying a lazy afternoon at their house when they hear the terrible news: Princess Peach has been kidnapped! The two brothers head straight for Bowser's castle to get her back, but Bowser is just as surprised about Peach's kidnapping as they are. At that moment, a strange top-hatted villain warps in and abducts everyone but Mario. The mysterious villain then forces Peach and Bowser to get married, creating a rift of dark energy that threatens to tear the universe apart. Only Mario can save the day ... but he can't do it alone.
