Layout
This level starts in an area with some Parabones, as well as some bridges which reveal spikes in a set pattern. A nearby Warp Box takes the player to an area filled with more Parabones, Fire Bros., and the aforementioned bridges. Another Warp Box brings the player to the Checkpoint Flag and a Warp Box which leads to an area with more Parabones and spiky bridges. The player will eventually need to hop on a spiky moving platform which leads them to an area which houses the Goal Pole.
