Boil the Big Bully
From the Super Mario Wiki, the Mario encyclopedia
The player has to first make it to the back-center platform with the Big Bully on it. From the start of the level, the player needs to take the left path at each split, then follow the platforms to the square platform with the Big Bully on it. To defeat the Big Bully, the player has to push it into the lava, with each attack pushing it backward. The Big Bully will attempt to do the same to the player character. When the Big Bully is shoved into the lava, it will sink and the Power Star will appear on a tall black platform nearby. Stairs will appear to help the player up, but the stairs will fall when the player jumps onto them.
