Burnstone Flowfalls is the 3rd level in Koopa Planet. It is unlocked via completing 8-2: Jet Airship and finishing that will unlock 8-Tower: Factory Tower. This level takes place in a lava field filled with Bob-ombs and lava spouts.
- At the start of the level, carefully use the sinking blocks to reach the coin.
- Just before the checkpoint, you'll find the coin under some Doughnut Blocks, but there's a lava spout there. Wait for the lava to stop before riding down to the coin.
- Just before the flagpole, you'll find an orange warp pipe. Take it to find a secret area. Once inside, quickly activate all 3 switches before the block fully sinks to break the blocks blocking the coin.
