World 9-8 (New Super Mario Bros. Wii)

World 9-8 is the eighth level of World 9 in New Super Mario Bros. Wii. It is unlocked by collecting every Star Coin in World 8. World 9 levels do not have to cleared sequentially. The most prominent features of the stage are the bouncing clouds and the King Bills, which only appear in this stage.

Layout
The last stage of the game is a sky level reminiscent of Coin Heaven. In it, the "floor" is made of several Bouncy Clouds that let Mario jump every time he falls on them. A little ahead, two ? Blocks are found, one of which contains a Propeller Mushroom. A little more forward, the first Star Coin is found surrounded by Fuzzies and after this part, a Roulette Block is found surrounded by five Fuzzies, one being big. Below them, a ? Block from the right contains a Mini Mushroom that can help the player to access high places. After that, the second Star Coin is found alongside several Fuzzies.

Forward, King Bills begin to break down walls so Mario can continue his progress. The level forewarns the player of the King Bills with large Bullet Bill-shaped coin formations. The third Star Coin is found stuck between walls that a King Bill destroys. Arriving at the end of stage, a last King Bill appears near the Goal Pole, where it can be destroyed if the player jumps on the flagpole before being hit by it. A P Switch found in a nearby Brick Block indicates this last King Bill with a Blue Coin arrangement instead. This course has the background from World 7.

Star Coins

 * Star Coin 1: Not long after the beginning of the level are three rail-riding Fuzzies surrounding the first Star Coin, along with several other Coins. Mario and co. must jump to the Star Coin from a Cloud at the right time to avoid touching any Fuzzies.
 * Star Coin 2: After the area with the first P Switch and several Brick Blocks, the second Star Coin is rail-riding behind three Fuzzies. Mario and co. must again jump from a Cloud at the right time to get it without touching a Fuzzy.
 * Star Coin 3: The third Star Coin is blocked off by many blocks in the area where two King Bills emerge and break all of the aforementioned blocks. Mario and co. must wait for the King Bills to destroy the blocks, then fall to the Star Coin.
