Super Mario 64/Lethal Lava Land

This stage is found in the basement. In the main room, there is a painting of a fireball. Go in to reach this stage.

Star 1: Boil the Big Bully
From where you start, long jump the gap, then take two lefts. Go across the puzzle pieces, then head right to find the bully. To get the star, knock the bully off into the lava. The star will appear on a nearby platform, but the ones leading to it will fall, so be careful.
