Rolling Coaster Galaxy

The Rolling Coaster Galaxy is one of the many galaxies found in Super Mario Galaxy 2. Like its name implies, this galaxy is like a roller coaster and, like in Rolling Masterpiece Galaxy, the player must roll a Star Ball to the end. Also, many Starshrooms appear along the way. It seems to be a reference to the Rainbow Ride level in Super Mario 64 and the Rainbow Road courses in the Mario Kart series. The name of the first mission in this galaxy confirms this. This galaxy uses the same music from The Princess's Secret Slide, Tick Tock Clock and Rainbow Ride levels in Super Mario 64, which speeds up as the Star Ball rolls faster.

Partway through the level, the path splits in two. One of the Toads says that the right path is for experts, while the other is assumed to be for beginners. In the "Purple Coins on the Rainbow Road" mission, the path for experts is the only path present. The Comet Medal is also on this path. The only enemies found in this galaxy are Bob-ombs and Goombas.

Rather than being separate planets, this galaxy is connected by chutes which allow the player to access the different paths and platforms.

The player will start on a simple orange and red platform. There is nothing of significance here besides the Star Ball, some coins, and a chute that takes the player to the next area.

This is a simple path that consists of colored tiles. There are no hazards on this path. It eventually drops the player off at an area where two roads diverge in different directions. Bob-ombs are found at the end of the pathway.

Taking the left path at the junction takes the player to this area. It is covered in beige tiles and is infested with Round Goombas and Bob-ombs. The edges of the path are concave, meaning that the player cannot fall off the edge unless blasted off by a bob-omb. This pathway is also wider than the other one and has more undulations. At the end of the path, the player will be dropped off at Rainbow Road Path 2.

Taking the right path at the junction takes the player to this area. It is a narrow, rainbow-tiled pathway. There are numerous beams found on the edges of the path, which will bounce the player off course if they were to come in contact with it. There are a few bob-ombs here and the Comet Medal is also found here. At the end of the path, the player will be dropped off at Rainbow Road Path 2.

This pathway is much like the first rainbow road pathway, except that it is more inclined and it sometimes gets narrow during certain times. The player will be dropped off at some pink and purple platforms where there will be a chute that takes them to the final path.

This pathway is more inclined than the others. The path also gets narrower as the player goes towards the end. The player will be dropped off at a grassy platform where there is a chute that connects to the final platform.

There is nothing of importance on this planet except for the hole which the Star Ball goes into. During the Purple Coin mission, there will be a Gearmo present.

The Rainbow Road Roll
To complete this mission, the player first needs to get on top of the Star Ball at the starting platform. Then, they have to use it to roll down the vgarious paths and platforms. They must avoid falling off the sides of the paths or running into Bob-ombs, which could cause them to fall off the side. When the player makes it to the Ending Planet, they will find a green hole. They must roll the Star Ball into it to release the Power Star.

Purple Coins on the Rainbow Road
When the Prankster Comet has been unlocked, the player will find a Purple Coin Ball at the starting planet as opposed to the normal Star Ball. The player must follow the same path as in the first mission, except for the fact that they will only be able to follow the path for experts when the course splits in two, instead of choosing either one to follow. Obviously, the player must also make sure to collect at least 100 of the 110 Purple Coins found on the Rainbow Road Planet with an imposing time limit of two minutes. If they are able to collect at least 100 Purple Coins within the time limit and successfully make it to the Ending Planet, then a Gearmo will reward Mario with a Power Star. If not, the player will have to start the level over.

Green Star 1
The first Green Star is located near the beginning of the level. The player should take the Beginner Path instead of the Expert Path. They have to do their best to stay in the middle and avoid to many Bob-ombs and Goombas. If done correctly, the player should have themselves rolling up a bumpy slope. Just before the player drops off the end of the slope, they must use the momentum of the Star Ball and jump into the air directly onto the star. If the player fails, they can roll right back up again (if he's careful), although the incline of the slope can make it rather difficult.

Green Star 2
The last Green Star is near the end of the final rainbow road path, just before the Ending Planet. It is positioned at the right side of the course, hovering in the air. In order for the player to reach it, they must either carefully use the momentum of the course to land on the star or jump before reaching the edge. If done correctly, the player should easily grab the star instead of falling off the course.

Trivia

 * The two missions in this galaxy are the only time in this game that the player can see all five of the Toad Brigade's Starshroom spacecraft at once; however, the Purple Coin mission of the Sea Slide Galaxy in the prequel features all five ships as well.
