Flipsville Galaxy

"Is that our captain?! How did he get way up there...?"

Flipsville Galaxy is the second level in World 4 in Super Mario Galaxy 2. It is home-themed, with a few dollhouse-like planets. The main gimmick in this galaxy is grates, which Mario can Ground Pound to flip the gravity and switch between the top and underside of each planet. This change is reflected by a screen of white arrows (similar to a gravity field) against the lavender sky, which always point to the direction of the gravitational pull. Mario can also use grates to defeat the Pupdozer enemy and its boss variation, Glamdozer, both exclusive to this area. The Spin Drill is available in later missions.

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 modeled after the interior of a dollhouse, featuring several rooms separated by wooden walls and the floor. 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 resembles a big white dollhouse, with Mario exploring its surroundings. 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 Both Side Lift 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. The next section involves a series of moving platforms with grates in the middle, which they must use carefully to avoid spikes. At the end of the planet is a generally small area. The only enemies here are two Pupdozers on the top and an Octoomba on the opposite side. The Launch Star among the Pupdozers will take the player to the Starshroom.

Starshroom
This Starshroom 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. As of this point, the sky becomes blue and the surrounding white arrows disappear.

Boss Bussun Planet
The Boss Bussun Planet is a flat, circular green planet with six grates and coins. The player fights Glamdozer here. Unlike the planets before it, Mario can travel between its sides alternatively by walking over the edge.

Both Side Drill Tower Planet
The Both Side Drill Tower Planet is a small patch of dirt 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. The music played here is Beat Block Galaxy's. This area is separated into nine sections like a 3×3 grid. Each room has its own gravity field, which cycles between two specific directions following the rhythmic signal of the background music. The player must use the Spin Drill here to find 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.

Alternatively, the player can also perform a homing ground pound to get the star, however the player should be positioned close enough to the star to avoid missing.

Prima Official Game Guide description

 * "Flipsville Galaxy has fun with the pull of gravity. You are usually pulled toward the floor, no matter which side of the planet you stand on. Use grates to flip back and forth between sides of the planets as you pursue the Power Stars."

Trivia

 * A glitch can occur in the first mission if the player gets to the second planet, touches the Checkpoint Flag, backflips onto a nearby overhang, long jumps and spin to the first planet, and takes the Launch Star. About halfway through, Mario will lose a life.
