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

In World 8-1, Mario and Co. have to go through a volcanic area full of lava. Raining Debris fall from the sky. There are rising lava spouts, which block the players temporarily from progressing if they don't have the Propeller Suit. Also, a cloud of hot ashes will chase the players from the left to the right. The hot ashes will instantly take out the heroes on contact if they are too slow. There are also Buzzy Beetles in this level.
