Next is a path made up of disappearing and Red-Blue platforms with Roctos and spiked Sentry Beams, followed by blocks with electric rods moving along them. Afterward are a group of Pull Stars the player need to use to cross the chasm while avoiding more Paragoombas, Mikey Mines, and electrical barriers; to get to the Launch Star at the end of this area, the player needs to use the second to last Pull Star to propel themselves around the electric barrier.
