Flip-Swap Galaxy is a galaxy that appears in Super Mario Galaxy 2. It is located in World 1 and is based on levels from Super Mario Galaxy and Super Mario Sunshine. Performing a Spin Jump will make the red and blue Red-Blue Panels flip over and swap places. Chomps also appear on the red and blue platforms, along with other enemies, like Goombas. A Star Bunny also makes an appearance here and gives out a hint.
The Flip-Swap Planet is split up into five different areas, each with their own gimmicks and perks.
The first area of this galaxy is rather simple. It only consists of a few flipping panels that change when the player performs a Star Spin. The player simply needs to time their spins to reach the other side of the planet.
The next area introduces electrified, moving fences. However, these fences move rather slowly, so they should not be a huge nuisance. In the Think Before You Shake mission, the panels are attached to each other. However, during the Purple Coin Flip 'n' Sprint mission, the panels are spread apart, more electric fences are added, and the area is larger. The Goombas and Octoombas on the platform between Area 1 and Area 2 are gone as well during the Purple Coin mission.
This next area is rather small and the only real hazard featured here is a large Chomp that rolls around the red panels. During the Purple Coin Flip 'n' Sprint mission, an electric wire moving back and forth appears on the platform connecting this area with Area 2.
The final area features faster moving electric fences and the panels are also spread out. During the Purple Coin Flip 'n' Sprint mission, the electric fences are replaced with two fast-moving electric wires that move across two separate sections of the area.
Green Star 1
This star is found above one of the red platforms in the second area. The player has to perform a Triple Jump and Spin or a well timed backwards somersault and Spin to reach this Green Star. If the player misses the star, then they can try again if they manage to land on the platforms which will be flipped from the Star Spin.
Green Star 2
This Green Star is found above a red platform where the Chomps are rolling around in the fourth area. The player has to perform a Triple Jump or a well timed Somersault to reach it while avoiding the Chomp that spawns nearby.
