Clockwork Ruins Galaxy

Clockwork Ruins Galaxy is a galaxy appearing in the game Super Mario Galaxy 2. It is located in World 6. The galaxy takes place in a temple-like area, with statues of many creatures. The galaxy includes some new gimmicks such as rolling platforms and walls that push Mario out of the gravitational force. Pegs are also introduced in this level and is used to reach the Power Star. The main obstacles here are spikes and Mario getting crushed by millstones. Common enemies here include Jack O' Goombas and Octoombas.

Starting Planet
The Starting 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 will protect the player if they fall off. Under the fourth millstone is a Hungry Luma which will require the player to feed it 30 coins. If they do so, they will be taken to the Ledge Hammer Planet. If not, they could take the Launch Star to the Pushing Wall Planet.

Pushing Wall Planet
The Pushing 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, causing them to fall into a Black Hole, similar to that of a Pushy Wall. The objective is to free the Luma that is trapped in a cage. The player will need to climb to the top left where they should find a switch similar to those found in Gusty Garden Galaxy from the first game. After the player hits the switch, the walls will fall apart and the gravity will change. The player will need to make their way to the ground pound switch on the bottom, freeing the Luma. The Luma will transform into a Launch Star and take the player to the Millstone Planet.

Ledge Hammer Planet
The Ledge Hammer Planet is accessed by feeding the Hungry Luma thirty coins on the Starting Planet. The planet is only visited during The Ledge Hammer Trap mission. It is a planet that has six Ledge Hammers on it. Getting hit by a Ledge Hammer will make 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 Time Switches found here and are helpful when trying to get to the other side. After the player passes the first Ledge Hammers, they will find a green Warp Pipe which will take them to the upper area of the planet. The same five ledge hammers are found here, but this time, the cracks in the wall will show where the ledge hammers will hit. There are no switches up here to slow down time. At the end of the upper area is the Power Star.

Millstone Planet
The Millstone 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. They can wall jump off of 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 will need to use the millstones to reach the pegs and finally the Power Star.

The Adventure of the Purple Coins
The player will have to collect the one hundred Purple Coins scattered across the Starting Planet. The player has only five minutes to collect the coins. Unlike in the regular level, no enemies are present. This level is time-consuming as the coins are on all sides of the millstones, and a few rotations will be needed before each one is done. After collecting the coins, the star will appear on top of the fourth millstone. Time right and jump when Mario is at the highest point to grab the star.

The Ledge Hammer Trap
The player will need to first collect 30 coins on the Starting Planet. After they have the amount, they should go feed the Hungry Luma that is located beneath the fourth millstone. The Luma will then transform into the Ledge Hammer Planet, which the player should travel to. When they land, they will notice some monstrous-looking mallets hitting the ground below and the wall above. The player will need to carefully navigate through the first part and take the Warp Pipe to the second area. There are Time Switches throughout the area, so the player can slow the Hammers down. They will need to dodge the hammers and reach the Power Star at the end. However, Luigi has it much easier, as with his bettter jumping he can simply backflip, spin, walljump, and spin again from the starting point to reach the star.

Green Star 2
The player will redo the Time for Adventure mission. The second Green Star is located on the Pushing Wall Planet.

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 them towards the border. The Green Star is on the top right corner.

Trivia

 * The Luigi ghost in this stage oddly preforms a glitch from the previous game where if Luigi backflips on to the Fountain's poles, then spin-ground pound, they will be stuck on it with Luigi on one foot.
