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.

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.

• Players run through vibrant 2-D worlds, stomping on enemies and breaking blocks ... then, with the press of a button, they flip into 3-D. In the third dimension, they'll find hidden paths, battle foes and uncover secrets as they explore the previously invisible depth of the 2-D landscapes.
• Hold the Wii Remote sideways and control the game in classic Super Mario Bros. style. Players can shake the Wii Remote to pull off stylish moves and break out of frigid ice and even point directly at the screen to get helpful hints from their sidekick. Not only that, but they'll also play as Peach and Bowser, both with their own sets of essential skills.
• When a mysterious villain kidnaps Peach and Bowser and forces them to get married, their union creates a rift of dark energy that threatens to tear the universe apart. Hilarious characters, laugh-out-loud plot twists and unforgettable dimensions await as Mario makes his way through eight chapters, each more memorable than the last.
