World 9-1 (New Super Mario Bros. Wii)

World 9-1 is the first level of World 9 from New Super Mario Bros. Wii. This level is sky-themed and is unlocked by collecting all of the Star Coins in World 1. The level uses the background of World 1 and plays the Athletic Theme. Like all levels in World 9, there is no Checkpoint Flag.

Layout
World 9-1 is an athletic level with a layout similar to that of World 7-1. There are a number of spinning rectangle platforms around the level. Also appearing is a giant spinning L-shaped platform. Koopa Paratroopas are the main enemy in this stage along with a number of regular Koopa Troopas.

Star Coins

 * Star Coin 1 (pictured): The first Star Coin is floating high above a platform with a red Koopa Troopa. Mario and co. can reach it by bounding off of the Koopa Troopa, or by using a Propeller Mushroom.
 * Star Coin 2: Soon after the first Star Coin, the second Star Coin is floating high above two Koopa Paratroopas and three rotating blocks. Mario and co. again must use either bound off one of the Paratroopas or use a Propellor Mushroom to reach it.
 * Star Coin 3: After the second Star Coin, there is a long Green pipe with a Fire Piranha Plant.  This pipe leads to a secret area.  Mario and co. must get on the rotating block and jump from it to a platform on the bottom right, which the third Star Coin floats over.
