Sky Station Galaxy

Sky Station Galaxy is a galaxy that in Super Mario Galaxy 2. The level begins with Mario flying through a series of clouds, eventually landing on a disc-shaped planetoid. The player can see Yoshi's House nearby, but he's not there. A Luma appears and tells Mario that the Power Stars have been stolen by a monster. The level is the introductory stage of the game, taking place before Mario lands on Starship Mario. The galaxy introduces the player to the gravity based gameplay and spherical planets of Super Mario Galaxy 2.

Yoshi House Planet
This is the starting planet for most missions in this galaxy. It is round and flat and divided into halves. The top half is grassy and Yoshi's House resides on it. The top half also contains two warp pipes, one green and one red. They both lead to the underside, but the red one transports Mario inside a cage with a 1-Up Mushroom inside. A hole in the middle of the planet can transport him to the other side. A fence lines the planet's perimteter. A Tip Network which shows how to star spin to defeat enemies is also seen on the underside of the planet. Enemies here include Goombas and Incoming Chomps in the second mission.

Grass Planet
This is a semi-large, grassy planet, which is home to many Octoombas. It is slightly rounded and it has a ? Coin, a Checkpoint Flag and a warp pad. Yellow platforms which will rises then turn blue and disappear are seen here which will lift Mario up to the Launch Star to blast him to the next planets. A Luma will guide Mario through this planet and will transform into a Launch Star when he gets to the end.

Cylindrical Planet
This planet is shaped as a cylinder with square platforms going around it. There is a Comet Medal here, and a few Paragoombas. There is also mud that will slow down Mario, and there is a black hole inside the planet. At the end is a Launch Star that will send Mario to the Geo Planet.

Bonus Planet
This planet looks like other bonus planets. Several Octoombas inhabit this planet and if Mario defeat all of them using the Rainbow Star within the time limit, three 1-Up Mushrooms will appear.

Geo Planet
This planet is very similar to the planet on which the player fought Dino Piranha on in the predecessor of Super Mario Galaxy 2. Peewee Piranha is fought on this planet.

Sky Fleet Ship
The Sky Fleet Ship appears in the second mission and it is a cylindrical, transparent planet with an inside with platforms, similar to the Pill Planet in the first game. The ship has a conical nose with a propellor at the tip. Banzai Bill Blasters launch Banzai Bills toward Mario or Luigi as they travel across the planet's glassy outside. A Rainbow Star is on the surface of the ship. Inside, there is platforming to be done and there is a warp pad and Launch Star inside.

In the first trailer of the game this planet had a lighter coloration.

Flip Switch Planet
A planet covered with Flip Switches. A Banzai Bill comes out of its blaster here, and in a second section Cosmic Clones appear.

Second Fleet Ship
There are three more Banzai Bill Blasters in this planet, and mud that makes Mario slower if he walks on it. There is a long platform on one side, and at the end of it is a Prickly Piranha Plant that Mario has to defeat in order to get a key to open a cage with the star.

Peewee Piranha's Temper Tantrum
After entering the Sky Station Galaxy, A Luma will appear and tell Mario that the Power Stars have been stolen by a monster. Mario has to collect the first Power Star. To do so, he must enter the green Warp Pipe which leads to the other side of the planet. Then break the Giant Crystal and fall into the hole. Then, he has to talk to a Yellow Luma who helps him by transforming into a Launch Star. Then, another Luma will show Mario the way. After arriving into a high platform, it'll turn into a Launch Star to blast Mario to a small group of planets. Here, he has to use the small jump and use the Sling Star to get to the third planet and use the launch star to blast off to the next one. Mario will need to follow the platforms towards the right while avoiding the black holes. At the end there will be another Luma who will lead Mario to the end of a fenced area and transform into a Launch Star to blast him to the next planet. The Luma in the other side will transform into a Launch Star to lead Mario to Peewee Piranha. After defeating the boss, he'll earn a Power Star.

Storming the Sky Fleet
If Mario returns to this galaxy after he defeats Peewee Piranha, he'll find Incoming Chomps in the first planet. But he'll find also a series of green plants that he can use to defeat the chomps. To get the Power Star, Mario must get to the other side of the planet, defeat an Incoming Chomp, get the dropped key, free the Luma who transforms into a Launch Star that Mario should use to process.

Mario then finds himself on a ship planet, he has to find the Launch Star hidden in this planet and use it to get to another area full of Flipswitches.To process, the plumber has to activate all the Flipswitches. If done so, a new series of them will appear. He has to do the same thing here, but he'll be chased by Cosmic Clones. After hitting all the panels, a Launch Star will appear.

After using the Launch Star, Mario will get to the area with the Power Star. But, it is in a glass cage. To open the cage, he has to defeat the Prickly Piranha Plant, take the key, open the cage and get the Power Star.

Peewee Piranha Speed Run
This mission is the same as the first one, only there is a 20 second time limit. Mario has to make his way to Peewee Piranha with getting clocks to increase time. If he defeats the boss before time runs out, he'll get a Power Star. Some of the planets are cut out.

Green Star 1
This Power Star is located on the Yoshi House Planet, near Yoshi's House. Mario or Luigi have to backflip to reach it.

Green Star 2
To get Green Star 2, the player needs to jump, near the Grass Planet's Launch Star, in an abyss. If he/she did correctly, before Mario or Luigi reaches the Black Hole, it will pick a Power Star.

Green Star 3
It is located over the Sky Fleet Ship's Warp Pad. The player needs to stand on it and do a backwards somersault to get it.
