The Flip-Out Galaxy is a galaxy that appears in Super Mario Galaxy 2, and is located in World S. It is unlocked by feeding the Hungry Luma 2,000 Star Bits, and is the final galaxy that can be unlocked before the player obtains 240 Power Stars. The galaxy uses the same concept as the Flip-Swap Galaxy from World 1, except that instead of controlling Red-Blue Panels, the player controls Reversible walls. In this regard, it combines the mechanics of the Flip-Swap Galaxy with Wall Jumping. The player needs to use the walls to their advantage in order to progress through the level. Common enemies here are Spoings, Choppahs, and Cosmic Clones, the last of which appear only in the second level. This is the only galaxy where a Green Star is found in a Prankster Comet mission.
The galaxy's name may come from the idiom "flip out", meaning to lose control of oneself.
Planets
NOTE: Unless otherwise noted, all names are unofficial.
Starting Planet
A small planet with two Star Bunnies to explain how to use the walls, a 1-Up Mushroom and a Warp Pipe that takes Mario to the Flip Wall Planet. There are a few walls that either go inside the wall or pop out of the wall. Mostly, this planet is for preparing Mario for the next planet.
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 Spoings can hinder him. Then 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, mostly at the wall jumping part near the end of the level.

Green Stars
Green Star 1
The first Green Star is found a little off the Starting 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 found in the Cosmic Clone Wall Jumpers mission. Right near the end of the level, the player has to wall jump off the last red wall and avoid spinning the blue wall. If timed right, Mario should land onto the star. This Star is easier to get if the player gets rid of the Cosmic Clones first.

Prima Official Game Guide description
- "This is one of the galaxies in the cosmos. You must spin to swap colorful blocks in the galaxy, creating a series of walls to jump up. The catch? Most of the planets in this galaxy have limited or no floors, so you better be at the top of your game if you want to nab the Power Stars here."

Trivia
- The Switcheroo level from Donkey Kong Country Returns is very similar to this galaxy. In both, players have to use reversible walls.
