Third Course (Coin Challenge Pack C)
From the Super Mario Wiki
The level begins with a Warp Pipe leading to a shaft with a bone coaster. Mario must keep going down while avoiding the volcanic debris coming his way. After the Checkpoint Flag, Mario must go up a second shaft while avoiding more volcanic debris, as well as hitting a few POW Blocks along the way with either a Super Leaf or a Gold Flower. The path eventually leads directly to the Goal Pole.
