Captain Toad — previously seen in Super Mario Galaxy — has a starring role in the forthcoming Super Mario 3D World. He takes part in exclusive levels where he has to traverse various obstacles in order to grab as many stars as possible.
The unique thing about Captain Toad's challenges is that he can't jump. Another major difference between these levels and the main game is the ability to alter the viewpoint using the GamePad's motion control — this can be overridden by the analogue stick, however.
We've grabbed some footage of the first Captain Toad level for your own personal amusement - rest assured, this is relatively simple when compared to the later ones.
