World 8-3 (New Super Mario Bros. Wii)

World 8-3 is the third level of World 8 in New Super Mario Bros. Wii.

Layout
The level starts out in a cavern full of lava. Throughout Mario and company must contend with giant lava waves that will defeat them upon contact. Hanging over the lava are chained platforms that sink when one of the characters step on them; these platforms can be found throughout most of the level's first half, with Koopa Troopas and Koopa Paratroopas placed on or around them. Shortly after the checkpoint is a series of tunnels that require the heroes to weave through incoming lava waves to pass safely. Following the tunnel is a series of weighted platforms that also sink if weight is applied to them. Flame Chomps guard the area. At the end is a Warp Pipe that takes players to the level's flagpole.

Star Coins

 * Star Coin 1: Shortly after the beginning of the level, the first Star Coin is floating under the second chain-hanging platform. Mario and co. must stand on the left side of the platform at the right time to descend down to the Star Coin without touching the Lava.
 * Star Coin 2: The second Star Coin is located in the narrow area shortly after the Checkpoint Flag, floating under a platform with a few other Coins. Mario and co. must wait for any Lava waves to pass, then walk to it.
 * Star Coin 3: The third Star Coin is right near the level's second Flame Chomp. Mario and co. must again wait for any Lava waves to pass, then jump to it.
