Breaking the Laws of Gravity
In this mission, Mario must get through areas where gravity switches back and forth. Obstacles like Thwomps get in the way. The Power Star is surrounded gravity changes, causing Mario to go in a square-like formation.
The Great Crate Incinerator
Not too long after beginning the stage, there is a Warp Pipe on the ceiling which can be accessed by flipping a switch, causing the gravity to make Mario walk on the ceiling. Once getting into the Warp Pipe, there is a room full of crates. In the middle is the Fire Flower, which transforms Mario into Fire Mario. After turning into Fire Mario, he must destroy crates using Fire Mario's Fireballs. Once finished (noting the next Warp Pipe is under a crate, and that there are coins in other crates and a 1-Up Mushroom in one crate), Mario will enter another Warp Pipe. After Mario talks to the Gearmo, which says that it is sick of "all this trash" it asks Mario to destroy all the trash crates in 20 seconds with the Fire Flower. After Mario does so, he is rewarded with a Power Star.

- After the green pathway section, you can backflip onto the side of the planet and find a 1-Up Mushroom hidden 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 just a lot less old-fashioned.
- This galaxy shares some similarities with the Battlerock Galaxy from the previous game. Both galaxies have a similar, yet more challenging counterpart galaxy later in the game (the Dreadnought Galaxy and the Upside Dizzy Galaxy) and both contain a mission where Gearmo asks Mario/Luigi to clear out trash.
