Flip-Out Galaxy

Flip-Out Galaxy is a galaxy that appears in Super Mario Galaxy 2. The galaxy is located in World S. It is the final galaxy unlocked before the player obtains 240 Power Stars. The galaxy uses the same mechanics as the Flip-Swap Galaxy except in that instead of platforms, the player controls giant walls colored red and blue. The player needs to use the walls to their advantage in order to progress through the level. The only enemies here are Scuttlebugs.

Starting Planet
A small planet with two Star Bunnies, a 1-Up Mushroom and a Warp Pipe that takes Mario to the Flip Wall Planet. There are a few walls that come out of the walls or get inside them when Mario spins.

Flip Wall Planet
A big, sidescroller planet with walls that change each time Mario spins, just like the first one. In the first section, Mario must jump on some platforms without much problem until he gets to the second section, where he must do the same, though some Choppahs can hinder him. In the last section, after going through some Scuttlebugs can hinder him. Thn he must avoid some spikes while and do some complicated wall jumps while changing the walls' position to avoid falling. In the second mission, Cosmic Clones will follow Mario, making it more difficult.

Wicked Wall Jumps
Mario first starts off onto the starting planet. After practicing how to control the spin-activiated walls, mario enters a pipe leading straight to the Flip Wall Planet. Here, he must travel up the flip walls by means of hopping or even wall jumping. Soon, Mario will reach a spike trap area where he must carefully time his movements to make it safely over. Afterwards, Mario was once again deal with flip walls while avoiding Choppas. Next, the player will find Mario once again facing eight sets of spikes he must avoid. What is challenging is avoiding the flip walls at the same time making sure he doesn't touch the spikes. Soon, Mario will end up at the hardest part of the coarse. The player was carefully guide wall jump Mario along the blocks, being wiseful of when to spin in mid-air to activate a different color block to wall jump off of. By the end though, Mario makes it to the top, break open the star from the cyrstal, and complete the level.

Cosmic Clone Wall Jumpers
Once again, Mario was deal with all the stuff he dealt with in the Wicked Wall Jump in this level. Yet it comes with a more challenging level as the Cosmic Clones brought by a Prankster Comet follow closely behind you. The Cosmic Clones are restless as they stay with Mario throughout the entire level. Complete all the Starter planet and the Flip Wall planet and free the star to end the raid of the Cosmic Clones. Grab the star to complete the level.

Green Star 1
The first green star is found a little off the Starter planet. All Mario has to do is wall jump between the first red wall and the blue wall to the top of the blue wall, make his wall through the second red wall onto the edge of the planet. There, the player has to have Mario drop down off the platform and aim carefully to land onto the star.

Green Star 2
The second green star is more challenging to obtain. Right near the end of the level, the player has to wall jump of the last red wall and avoid spinning the blue wall. If timed right, Mario should land onto the star.
