Super Paper Mario is an all-new adventure with a new villain -- and the same great role-playing action. Princess Peach is kidnapped again, and Mario & Luigi Head over to Bowser's Castle. Only Bowser's not involved this time! A mysterious villain appears then and 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! What starts as a 2D side-scroller like Paper Mario universe soon turns into a hilarious dimension-shifting platformer possible only on Wii.
