World 7-3 (New Super Mario Bros. Wii)

World 7-3 is the third level of World 7 in the game New Super Mario Bros. Wii. There are Fuzzies and Big Fuzzies on this level that move on rails. There are also a lot of platforms that move on rails.

Layout
Mario starts the level near a track with a Fuzzy, a brick, and a ? Block containing a Propeller Mushroom. A Mushroom Platform with more bricks and ? Blocks is found, followed by track with a ? Block and two Fuzzies on it. After another track, Mario must ride a lift across a track. Several Fuzzies fall onto the track, and they must be jumped over. The midway point is then found, along with a Mushroom Platform with two ? Blocks above it, one of which containing a Propeller Mushroom. Two more groups of Fuzzies on tracks are found, along with a track with Fuzzies, bricks, and ? Blocks on it. A P Switch is found on a Mushroom Platform, and causes Blue Coins to appear when pressed. Mario must then ride across more lifts, avoiding Fuzzies and Big Fuzzies. A Roulette Block can be found above a Mushroom Platform. At the end of the track, the flagpole is found.

Star Coins

 * Star Coin 1: Shortly before the first rail ride, the first Star Coin is riding rails with two Fuzzies. Mario and co. must make a well-timed jump to get it without touching a Fuzzy or falling.
 * Star Coin 2: In the area with several rail-riding Fuzzies, bricks and ? Blocks (pictured), there is a hidden block with a vine over the yellow flower on the left-most blue mushroom platform. This vine leads to an area with several coins, a P Switch and the second Star Coin. Mario and co. must activate the P Switch to turn the coins into bricks and use them to get to the platform with the Star Coin.
 * Star Coin 3: The third Star Coin is in plain sight on the second-last rail ride and can be easily jumped to.
