World 8-2 is a level found in the game New Super Mario Bros. Wii.
This level contains more falling debris and spinning wheels on the ground. As soon as Mario and co. enter the pipe, they end up in an underground area filled with more lava. Goombas and Paragoombas will appear many times on this stage, along with the spiked balls. The team have to dodge the obstacles to get through. This level also has a secret exit.
- Star Coin 1: The first Star Coin is high up in the area where the first Giant Spiked Ball appears. Mario and co. must use the platforms to reach it.
- Star Coin 2: The second Star Coin is hidden in the wall to the bottom-right of the two Pipes from which Goombas emerge.
- Star Coin 3: At the end of the level, there is a hidden area under the exit Pipe. The third Star Coin is in this area.
Directly after the second Star Coin, there is an area with several spinning wheels and Spiked Balls. At the end of it, turning left reveals a hidden area that leads to a Green Pipe. This Pipe leads to an area with more, faster spinning blocks that can only be traversed by jumping. Once at the end, avoid the Goombas and jump up to the Pipe which leads to the secret flagpole.
