Rightside Down Galaxy

Rightside Down Galaxy is a galaxy that appears in Super Mario Galaxy 2. The galaxy features gravity changes, represented by arrows in the background, much like the later Upside Dizzy Galaxy. Part of the galaxy may be played upside down, frontways (which is visually the same as a top-down view), and other directions. Enemies that appear in this galaxy include Goombas, Paragoombas, Prickly Piranha Plants, Thwomps, and Chomps. The music changes depending on the direction of gravity. The Fire Flower makes its first appearance in this galaxy.

The outside of this planet has four structures shaped like wooden toys and has a warp pipe leading inside the planet. The inside of this planet is made up of wooden blocks and has Gravity Walls that change depending on the player's actions or the place where he is standing. The Toad Brigade is found at the beginning of the planet. A Warp Pipe in the ceiling at the beginning of the level leads to a small area with a Fire Flower and crates. This planet is infested with Swaphoppers and Goombas. The first part of the planet consists of a linear road with a few levers that need to be hit in order to change gravity. As the level progresses, more dangerous enemies like Thwomps and Chomps will be present and there will be platforms that take the player dangerously close to Black Holes. Some Fling Flowers positioned at various locations inside the planet aid the player in reaching different areas. Halfway through the planet, the player will need to burn the crates with the Fire Flower. The gravity will change after the player progresses past this point and large gaps will be present. At the end of this planet, there will be more Thwomps and the Power Star at the end.

This is a simple, metallic, half-sphere planet. A Gearmo inhabits this planet and asks the player to use the Fire Flower to burn all the crates in twenty seconds for a Power Star in Crate Burning, similar to the Bob-omb Blasting minigame in the first game. The fireball can go through several crates at once. After burning through all the boxes, Gearmo will give a Power Star to Mario, the Hidden Star of this galaxy.

Starshrooms
Two Starshrooms, a yellow and a red one can be seen around the, though they are not accessible.

The Great Crate Incinerator
The player must change the gravity to reach a pipe in the ceiling near the beginning of the level. Inside this room, they must burn some crates with the Fire Flower to find a pipe. The pipe is located at the top right corner. This will take the player to a planet full of crates where they can ask a Gearmo to burn them in twenty seconds in the Crate Burning minigame to get the Power Star.

Green Star 1
The player will redo the Breaking the Laws of Gravity mission. Green Star 1 is located right after the third checkpoint and right before the green puzzle pieces area. Getting the star requires a well-timed jump and spin from the green block area or a precisely timed wall-jump from in between the two areas.

Green Star 2
The player will redo the Breaking the Laws of Gravity mission once more. Green Star 2 is found in the second Thwomp area (the one near the Power Star at the end). One must jump on top of the last Thwomp and then jump over to the Toad next to the Item Crystal of Star Bits. The star requires a really high jump to get, which the player can perform by executing a Side Somersault to the wall, Wall-Jump, and spin.

Trivia

 * After the green pathway section, one can backflip onto the side of the whole planet and find a 1-Up Mushroom in each of the four corners.
 * The background of the house in the start of the level, right after the player has entered the Warp Pipe, is very similar to the Palace of Shadow as shown in the intro of Paper Mario: The Thousand-Year Door.
