The player starts on a platform with a Yoshi Egg. Breaking Yoshi out of it, the player needs to use him to cross the Flower Grapples and avoid the Floating Mines, Paragoombas, and Bullet Bills to reach the Launch Star at the end. Next is a series of Flipswitch Panels the player needs to activate while avoiding Sentry Beams to create a Launch Star. In the Electric Maze Area, the player needs to utilize a Cloud Flower power-up to ride the winds and avoid the electric barriers to reach the Launch Star at the end. Next is a path made up of disappearing and Red-Blue platforms with Octopodes 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, Floating 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. Finally, the player will have to cross platforms with Hammer Bros. and Boomerang Bros. with Flomps bridging the gaps. Defeating the three Boomerang Bros. at the end will cause the Power Star to appear.
