World 8-1 (New Super Mario Bros. Wii)

World 8-1 is the first level of World 8 in New Super Mario Bros. Wii. It is a volcanic level full of lava, and is the first to feature lava geysers. Volcanic debris falls from the sky and a cloud of ash follows the players from the left to the right.

Layout
This level is completely filled with lava. An ash cloud chases Mario from the start to the end of the level, slowly consuming the entire level. If Mario or any of the others touches the cloud, they instantly lose a life. Volcanic debris also falls from the sky, and geysers of lava will erupt periodically from their lava pools. Various metal platforms can be found floating above the lava which slowly sink if stepped on; once Mario and co. are no longer standing atop the platform, it rises back to its original position. Buzzy Beetles are very common in this level, and are the only non-obstacle enemy present.

Star Coins

 * Star Coin 1: Not long before the midway point is a long platform, and the first Star Coin is to its high right. Mario and co. must wait for the platform to tilt all the way to its left and then jump off the raised right end to get the Star Coin.
 * Star Coin 2: Mario and co. must pick up the POW Block and activate it near the row of three Brick Blocks and two ? Blocks before they are destroyed by volcanic debris. The second Star Coin will then fall within reach..
 * Star Coin 3: Instead of exiting with the usual green Warp Pipe, Mario and co. must go past it. Once there, they can obtain the third Star Coin by destroying the Brick Blocks surrounding it (or allowing the volcanic debris to do so) and use a trampoline to jump up and collect it.
