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

World 9-8 is the eighth and last level of the ninth world in New Super Mario Bros. Wii. It is unlocked by collecting every Star Coin at World 8. It is the only level in the game to have King Bills.

Layout
The last stage of the game is a sky level. In it, the "floor" is made of several 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 5 Fuzzies, one being a mega. Below them, a ? Block from the right contains a Mini Mushroom that can help the to access high places. After that, the second Star Coin is found alongside Fuzzies.

Forward, King Bills begin to break down walls so Mario can continue his progress. 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. This course has the background from World 7.

 * If the player jumps on the P Switch before the flagpole, Blue Coins appear in the formation of a King Bill. This is the evidence of why an unexpected King Bill appeared.
