Clockwork Ruins Galaxy
The Clockwork Ruins Galaxy is a galaxy located in World 6 appearing in the game Super Mario Galaxy 2. It is a ancient ruins-themed location featuring several stone structures as planets, often times decorated with face carvings, grass and trees. The galaxy includes new gimmicks such as rolling millstones and walls that push the player out of the gravitational force. Pegs are also introduced in this level. Only Goomba enemies are found here, and they include Jack O'Goombas and Octoombas.
The music in this galaxy is the same as the music in the Slipsand Galaxy. They also share the towers in the background.
Giant Rotation Planet
The Giant Rotation Planet is where the player first lands. Two Jack O'Goombas are encountered at the beginning. The planet consists of four odd shaped millstones that the player must use to get to the Launch Star at the end. Many Octoombas are found on the millstones. At the bottom of the second and fourth millstones are areas of land which protects the player if they fall off. Under the fourth millstone is a Hungry Luma which requires the player to feed it 30 coins. If the player does so, the Luma can open the passage to the Huge Hammer Planet. If not, the player can take the Launch Star to the Pusher Wall Planet.
Pusher Wall Planet
The Pusher Wall Planet is filled with Jack O'Goombas. As the name suggests, the planet's main obstacle is the wall's ability to push the player out of the planet's gravitational force to a black hole, similar to that of a Bomp. The objective is to free the Luma that is trapped in a cage. The player needs to climb to the top left where a switch similar to those found in Gusty Garden Galaxy from the first game is located. After the player hits the switch, the walls fall apart and the gravity changes. The player needs to make the way to the ground pound switch on the bottom, freeing the Luma. The Luma transforms into a Launch Star and takes the player to the Rolling Drum Planet.
Huge Hammer Planet
The Huge Hammer Planet is accessed by feeding the Hungry Luma thirty coins on the Giant Rotation Planet. The planet is only visited during The Ledge Hammer Trap mission. It is a planet that has six Ledge Hammers on it. Getting flattened by a Ledge Hammer makes the player automatically lose a life. The ground moves in a circular pattern and has many pieces of it cut out. Electrical fences also appear on the planet. There are two blue switches found here that slows down time temporarily, and they are helpful when trying to get to the other side. There is also a 1-Up Mushroom that can be acquired by jumping onto the head of a Ledge Hammer after slowing down time. After the player passes the first Ledge Hammers, there is a green Warp Pipe that leads to the upper area of the planet. The same five ledge hammers are found here, but this time, the cracks in the wall show where the Ledge Hammers are hitting. There are no blue switches up here to slow down time. Another 1-Up Mushroom can be found above one of these Ledge Hammers. At the end of the upper area is the Power Star.
Rolling Drum Planet
The Rolling Drum Planet is the final planet in the galaxy. It is made up of three distinct areas. In the first area, there are millstones that fall from the sky and roll downhill. The player should use the indents in the stones to avoid being crushed. This specific area is where the Comet Medal is located. The second area consists of spiked ground and walls which the player must avoid. Pegs are also found here. The player can wall jump off the two millstones in the area to reach the final area. In this area, the player should take the elevator and hit the switch to make millstones fall from the sky. The player needs to use the millstones to reach the pegs and finally the Power Star.
Green Star 1
The player has to redo the Time for Adventure mission. However, when he or she gets to the third millstone on the Starting Planet, the Green Star is above it. The player can easily jump and Star Spin to get it.
Green Star 2
The player should replay the Time for Adventure mission. The second Green Star is located on the Pusher Wall Planet. The player needs to first change the gravitational force of the planet so they walking on the wall. The player can then do one of two things: they can either do a backwards somersault followed by a Star Spin to get on the borders of the level or just have a pushing wall push him or her towards the border. The Green Star is on the top right corner.
The early location of Green Star 2 was after the first set of millstones on the Starting Planet.
Green Star 3
The player should replay the Time for Adventure mission. This time, the final Green Star is located on the Rolling Drum Planet. The player needs to travel through the millstone planet until they reach the part where the Power Star is. The player should see the Green Star off to the distance. The player must climb onto a millstone to head towards the star. Once the player is close enough, he or she should perform a somersault followed by a Star Spin to reach the Star.
