World 9-3 (New Super Mario Bros. Wii)

World 9-3 is the third level of World 9 in New Super Mario Bros. Wii. This course has the background of World 6 and is unlocked by collecting all the Star Coins from World 3. It features Missile Bills and Missile Banzai Bills. POW Blocks cannot defeat these enemies. The floor resembles that of World 7-2.

Star Coins

 * Star Coin 1: After the onslaught of Missile Bills is a cloud-covered Green Pipe between two tall platforms with Koopa Troopas. The Pipe leads to a small maze-like area with a P Switch and the first Star Coin. The player has to activate the P Switch to turn the Brick Blocks into Coins and quickly traverse through the maze to the Star Coin before the P Switch's effects wear off.
 * Star Coin 2: After exiting the area with the first Star Coin, the player must go left and will see an upside-down Green Pipe with two coins high in the air. After getting in to the Pipe by jumping on Missile Bills is an area with another P Switch. The player must activate the P Switch and hurry along across the new Brick Blocks and jump to the second Star Coin before the effects wear off.
 * Star Coin 3: Midway through the area with no ground, several floating platforms and Missile Banzai Bills, the third Star Coin is floating high in the air. The player must wait for a Missile Banzai Bill to appear and jump on it to reach the Star Coin.
