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

World 9-8 is the eighth and last level of World 9 in New Super Mario Bros. Wii. It is unlocked by collecting every Star Coin in World 8. 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. 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 and one of those contains a Propeller Mushroom, which can improve a player's chance of survival greatly. A little more forward, the first Star Coin is found surrounded by Fuzzies and after this part, a Random Item 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 will destroy. Arriving at the end of stage, a last King Bill will appear near the flagpole 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.
