World 7-3 (New Super Mario Bros.)

World 7-3 is the third level of World 7 in New Super Mario Bros..

Layout
The level begins in an area with two Wigglers and two Warp Pipes. Upon entering the green Warp Pipe, the player ends up in an area where they must ride a giant Wiggler to reach the end of the stage. A Koopa Paratroopa is found, along with various coins and Hidden Coins. A Red Ring and another Koopa Paratroopa are also found. A Warp Pipe spawning Goombas follows, along with more coins. A Boomerang Bro and a Goomba are found before a ? Block that contains a Starman. Collecting the Starman allows the player to leave trails of Blue Coins when they move, with various ? Blocks allowing the player to create a chain of Starmen. More Koopa Paratroopas are encountered, as well as a second Warp Pipe spawning Goombas. After more Goombas and Koopa Paratroopas, a Boomerang Bro is found, along with a Warp Pipe leading to the pole.

 * Star Coin 1 - The first Star Coin is after the ? Block where the Starman is.
 * Star Coin 2 - The second is beyond the first in which the player must use a Koopa Paratroopa to reach.
