Nintendo has announced a surprise for those who have played Super Mario 3D world. If you have save data on your Wii U from the game, you’ll get to access to Captain Toad bonus levels — many of which are from Super Mario 3D World like Super Bell Hill and Conkdor Canyon. The content will be accessible to those without the game by collecting treasure and completing challenges in the story mode.

Captain Toad: Treasure Tracker will be released on December 5 exclusively for Wii U. Check out the latest footage here.
