The level begins with maces spinning plus Fishbones. Up ahead are some Bony Beetles, Dry Bones, and spikes. Rusty spikes will fall the moment you approach one. Go through either pipe and in the next room, there are more maces circling, Fishbones, Dry Bones, Bony Beetles, and Thwomps. Once you go far, enter the big red door to battle the boss. Reznor has 4 rhinos shooting fire as the wheel spins. Hit the platforms from below to knock off the rhinos. After 2 units are gone, the bridge below will collapse so find a safe platform to get on. After all 4 units are knocked away, you’ll finish the level.
