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 Bull's-Eye Bills and homing, Banzai Bill-like King Bills. POW Blocks cannot defeat these enemies. The floor resembles that of World 7-2.

Star Coins

 * Star Coin 1: After the onslaught of Bull's-Eye 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 Bull's-Eye 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 King Bills, the third Star Coin is floating high in the air. The player must wait for a King Bill to appear and jump on it to reach the Star Coin.
