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 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 five Fuzzies, one being big. 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.

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.

Enemies

 * Fuzzies
 * Big Fuzzies
 * Goombas
 * King Bills

Trivia

 * A group of Coins are in a formation similar to Waluigi's emblem.
 * 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.
