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, Purple Piranha Plants, Thwomps, and Incoming Chomps. The music changes depending on the direction of gravity. The Fire Flower makes its first appearance in this galaxy.

Inside this planet, shaped like wooden toys, the gravity changes depending on Mario's actions or the place where he is standing. A Warp Pipe in the ceiling takes the player to the Crate Planet. The Toad Brigade is found here. There is also another Warp Pipe that leads to a bonus area with a Fire Flower and crates. There is another Warp Pipe that leads to the Crate 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 mini-game in the first game. The fireball can go through several crates at once.

Breaking the Laws of Gravity
Mario must traverse the planet avoiding the enemies and shifting gravity. At the end he must use a Fire Flower to burn some crates and reach the star.

The Great Crate Incinerator
Mario must change the gravity to reach a pipe in the ceiling near the beginning of the level. There, he must burn some crates with the Fire Flower to find a pipe that will take him to a planet full of crates where he can ask a Gearmo to burn them in 20 seconds to get the star.

Green Star 1
Green Star 1 is located right after the third checkpoint and right before the green blocks area. Getting the star requires a well-timed jump and spin from the green block area.

Green Star 2
Green Star 2 is found in the second Thwomp area (the one near the Power Star). One must jump on top of the last Thwomp and them jump over to the Toad next to the crystal of Star Bits. The star requires a really high jump to get, which the player can do by doing a Side Somersault to the wall, Wall-Jump, and spin.
