Flipsville Galaxy is a galaxy in Super Mario Galaxy 2 located in World 4. The galaxy is home-themed, with many dollhouse-like planets. The main gimmicks in this galaxy are Flipping platforms known as grates, which Mario (or Luigi) needs to perform a Ground Pound to turn these platforms over and flip the gravity to gain access to different areas. Mario can also use the grates to defeat the Pupdozer enemy. A dinosaur-like boss named Glamdozer resides in the galaxy. The galaxy has some side-scrolling areas, where the Spin Drill is available. The galaxy has a lavender sky with many clouds. A bizarre screen of white arrows surrounding the galaxy shows the current gravity force affecting Mario (similar to a gravity field), which changes as the plumber pounds the grates. This is one of four galaxies in Super Mario Galaxy 2 in which the Wii Remote forewarns the player of upcoming obstacles, the other three being the Beat Block Galaxy, the Upside Dizzy Galaxy, and the Battle Belt Galaxy.
Both Side Maze Room Planet
The Both Side Maze Room Planet is basically one, giant dollhouse-like area. There are many grates that the player can use to go under the stage and vice-versa. Pupdozers are bountiful in this area. Some Octoombas can be found here along with the Comet Medal. The Launch Star is located at the top of the planet. During the second mission, the grates are absent and are replaced with dirt patches. Pupdozers are replaced by Micro Mecha-Bowsers and the Spin Drill appears in various places.
Both Side Wanwan Planet
The Both Side Wanwan Planet is another dollhouse-like area. The only enemies here are Chomps and Octoombas. The player can use the grates to their advantage to avoid being hit by a Chomp. The Launch Star at the end will take the player to the Moving Gate Planet.
Both Side Lift Planet
When the player lands on the Both Side Lift Planet, they will need to flip the gate to get to the underside of the planet. The player will need to wait for the moving gate to come by so the player can hop onto. The player will continue to ride the grates while avoiding spikes and jumping moving platforms to the end of this planet.
This planet is visited right before the fight with Glamdozer. Blue Toad can be found here to give Mario a hint as to how to defeat Glamdozer. The Prima Games guide mistakenly colors the Starshroom blue, but in the game, it's actually red.
Boss Bussun Planet
Both Side Drill Tower Planet
The Both Side Drill Tower Planet is two circles being transversed by a large dirt tower straight through the middle. The player must use the Spin Drill located behind the tower to get to the top where the Warp Pipe is. The only enemies here are Twirlips.
Timer Gravity Change Drill Room
The Timer Gravity Change Drill Room can be accessed by taking the Warp Pipe on the Both Side Drill Tower Planet. This area is separated into nine sections by the dirt. The music will change similar to that of Beat Block Galaxy's. After a certain beat, the gravity of the area will change. The player must use the Spin Drill to collect five Silver Stars in the second mission and 100 Purple Coins in the third mission. The only enemies here are Fuzzies.
Green Star 1
The player will redo the Flip-Flopping in Flipsville mission. This time, when the player gets to the Launch Star on the Both Side Maze Room Planet, they should look around for an edge of a wall that is glimmering. The player will need to stay close to the edge of the wall and fall down to get the Star.
Green Star 2
The player will redo the Flip-Flopping in Flipsville mission. When the player gets to the Both Side Wanwan Planet, they should avoid the first Chomp and use the gate to get to the second area. When the player reaches the circle with the Life Mushroom, they should notice a raised platform. The player must execute either a backflip followed by Star Spin or a wall jump and Star Spin to get the Green Star on the roof.
Green Star 3
The player will redo the Flip-Flopping in Flipsville mission. When the player gets to the end of the Both Side Lift Planet, they should notice the Green Star out of reach in the top right corner. The player must flip the grate to get under the level, causing the gravity to change as shown by the arrows. The player will then need to jump from the bottom right corner to get the star. If the player misses the Star, they will automatically lose a life.
