World 9 is the final world and a secret world of New Super Mario Bros. Wii. The world is set in space and on a giant rainbow star. Each level in the world is gated and cannot be played until all Star Coins from a certain world are found. Therefore, it is optional to play through. There are, just like most other worlds, eight levels. World 9-8, the final one, has giant Bullet Bills called King Bills. These things cannot be stomped on or defeated, but can be evaded. This world and Rainbow Road are very similar.

How to unlock

The World is unlocked when Bowser is defeated. Although, to unlock the levels, Mario must collect all the star coins in one world to unlock one level.
