World 8-3 is a level found in the game New Super Mario Bros. Wii.
This level takes place around a volcano with lots of lava. There are lava waves at the bottom of the screen throughout the level that instantly kill.
- 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.
