Nintendo has revealed a new feature in New Super Mario Bros. U, along with further info on the game's modes. The new feature concerns the little dude above, a thief called Nabbit. When this purple bunny/thing appears on the world map, that's your opportunity to catch the miscreant and rid him of his swag. If you successfully chase him down in the level, you'll return the stolen goods to Toad who'll reward you with a P-acorn that lets you fly endlessly, good for one stage.

Minus opportunities for lapine custody, New Super Mario Bros. U also features 'Boost Mode' as revealed at E3, the return of 'Coin Battle' from its Wii predecessor, and 'Challenge Mode.' Coin Battle is as it sounds, an up-to-four-player showdown to see who can collect the most coins across unique courses. It's compatible with Boost Mode, meaning one GamePad-wielding player can place blocks to help or hinder as he or she pleases. Challenge Mode is similarly self-descriptive, with tasks set in four categories: Time Attack, Coin Collection, 1-Up Rally, and Special. It's also compatible with Boost Mode.
