Sky Station Galaxy

Sky Station Galaxy is a galaxy in Super Mario Galaxy 2. The level is the introductory stage of the game, taking place before Mario lands on Starship Mario. Mario is launched into the galaxy from Princess Peach's Castle. After flying through a series of clouds, Mario eventually lands on a disc-shaped planetoid. 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 a round, small planet divided into two sides by a big white fence; a light side and a dark side (like the Starting Planet from the Good Egg Galaxy in the first game). On the light side there are several bushes with Star Bits and Coins and several mini goombas as enemies along with a big house that belongs to Yoshi. A note on the door asks Mario to come around back. Also on the top side of the planet are two Warp Pipes, one green and one orange. The orange one will lead Mario into a cage with a 1-Up Mushroom while the green one will lead him to the darker side of the planet.

The darker side is mainly a ring of dirt with numerous crystals and Goombas all around. In the middle of the ring is a giant mound of dirt with a crystal on top which, when broken, reveals a hole leading back to the top of Yoshi's House. In the second mission of the galaxy there are also Chomp Pups rolling in circles around the darker side of the planet.

Grass Planet
The Grass Planet is a large planet covered in grass. It is home to many Octoombas. The planet has one path going through it which a Luma leads Mario through. There are, however, outcroppings with different things such as an Octoomba, a ? Coin and a Teleporter which are just off of the path, it is hard to miss them. Yellow platforms which rise into the air and then disappear are introduced on this planet, they will reappear at the bottom again after they have disappear but they are used to lift Mario up in various points of the planet to get to the next area or, once, to get a 1-Up Mushroom. At the end of the planet the Luma that was leading Mario turns into a Launch Star and sends Mario to the Miniature planets.

Bonus Planet
The Bonus Planet is an hexagon-shaped planet with fences around the edge. It is accessed by spinning on the teleporter on the Grass Planet. There are seven Octoombas gathered around a stone platform in the middle with a Rainbow Star on it. Rainbow Mario must kill all of the Octoombas to make three 1-Up Mushrooms appear in the middle of the planet. However there is a time limit and Mario will be teleported back as soon as the time limit runs out, no matter how far he is in the progress of the planet's test.

Miniature Planets
The Miniature Planets are three planets floating together which have a few Coins. The first planet has several coins and is covered in grass and flowers meanwhile the second is covered in sand and has a Sling Star which sends Mario in a figure 8 pattern around the Miniature Planets. There is another Sling Star along the path of the first sling star and if Mario spins while in the range of the second sling star, he will get a ? Coin. However if he misses it he will land on the third Miniature Planet and not be able to go back. The third miniature planet is covered in dirt with a few rocks and coins and a Launch Star to the Cylindrical Planet.

Cylindrical Planet
The Cylindrical Planet is a grass-covered plant with several Paragoombas all along. The beginning of the planet has a Midway Flag and then leads down a path to a large moving stone platform going around the circle of the planet. It is possible to get a 1-Up Mushroom by staying on this platform all the way around. When Mario gets off he will have to make it through a few more Paragoombas before reaching the next moving stone platform which, if he stays on it, gives him a Comet Medal. He will then be able to travel through a final stretch of Paragoombas and get to a Luma which will become a Launch Star to the Sided Planet.

Sided Planet
This planet is a flat planet with a light side and a dark side. Both sides have a set of steps, the steps on the dark side are made of stone and the ground is brown. There is an Octoomba guarding a Life Mushroom and a checkpoint flag which Mario can get. The steps on the lighter side are covered in grass and there are Octoombas on each step along with a couple coins for Mario to get and a Launch Star at the top which leads to the Geo Planet.

Geo Planet
The Geo Planet is a brown planet with several crystals which contain coins strewn around it. It is similar to the Geo Planet from the Good Egg Galaxy in the first game. However, instead of Dino Piranha, Peewee Piranha is battled here. Peewee is in a gigantic egg on the planet when Mario lands there and must defeat it.

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.

Flipswitch Planet
A planet covered with Flipswitches. 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
Peewee Piranha's Temper Tantrum is the first level of the Sky Station Galaxy and, essentially, the first level in the game. It must be completed before reaching the Starship Mario. Mario begins the level flying through several clouds and lands on the Starting Planet. A Luma tells him that a monster stole their Power Stars and asks him to please get them back. He commits all Lumas to Mario's cause. Mario must travel around the starting planet to the green pipe which leads to the other, darker, side of the planet. On the darker side Mario must travel up the mound in the middle, break open the crystal and jump through to find that Yoshi is not actually there along with a Luma which turns into a Launch Star for him leading to the Grass Planet. Mario can also Wall Jump and then Spin up the side of the building to get on top. On the Grass Planet a Luma leads Mario through a path of Electrogoombas and rising platforms until he reaches the end and then it turns into a Launch Star to the Miniature Planets. The Miniature Planets are a few planets with a ? Coin and a few Sling Stars which eventually lead Mario to a Launch Star sending him off to the Cylindrical Planet.

On the Cylindrical Planet Mario must travel along the only path, riding the stone platforms around the planet whenever it needs to happen and just make his way to the other side of the planet where a Luma will transform into a Launch Star to the Sided Planet. On the sided Planet, Mario must go up the stone steps and get the Midway Point along with the Life Mushroom and then travel around to the other side and climb up the green steps to a Launch Star leading to the boss battle on the Geo Planet with Peewee Piranha. Upon landing on the Geo Planet, Mario cracks open Peewee Piranha's egg and releases the beast-piranha plant. Mario must Spin the shell on its behind twice and then attack its exposed bottom to damage it. After hitting its weak spot two times, Peewee Piranha will explode into purple smoke and release a Power Star for Mario to get.

Storming the Sky Fleet
The second level in the Sky Station Galaxy is Storming the Sky Fleet. Mario once again begins on the Starting Planet but this time around it is infested with Chomp Pups. Travelling to the darker side of the planet via the green warp pipe, Mario must use the green plants strewn around to open up the chests and find a Rainbow Star. Rainbow Mario must then run around and destroy all of the Chomp Pups on this side of the planet to get a key to free a captured Luma. The Luma will reward him by transforming into a Launch Star to the Sky Fleet Ship. The Sky Fleet Ship has multiple Banzai Bills for Mario to avoid before he can get to a hole which leads inside the ship. On the inside there are numerous Amps and moving platforms. Mario must travel to the other side of the moving platforms and take the Launch Star to the Flipswitch Planet. After Mario has pressed all the switches on the Flipswitch Planet, another section appears where Mario has to press the flipswitches but there is a slight problem; he is being chased by Cosmic Clones. After pressing all the switches the clones will disappear and a Launch Star will appear to the Second Fleet Ship. The Second Fleet Ship has numerous Banzai Bills blasting all around and a Power Star in a cage. Mario must travel to the end of the walkway, avoiding the Banzai Bills, and reach the end with a pole, two Piranha Plants and one Spiky Piranha Plant. Defeating the Spiky Piranha will yield a key which frees the Power Star and allows Mario to go back, still avoiding the Banzai Bills, and get his star.

Peewee Piranha's Speed Run
Peewee Piranha's Speed Run is a Prankster Comet mission in the Sky Station Galaxy. It plays out almost same way as Peewee Piranha's Temper Tantrum except there are ten green timers throughout the level which add ten seconds to Mario's time. Mario begins with 20 seconds on the clock and must continue collecting these timers to keep his time above zero. If the timer reaches zero, he will lose a life. In total, there are 120 seconds or two minutes on the clock with all the timers added together.

Another difference between this and the first level is that the Grass Planet, Miniature Planets and Side Planets have all been left out to conserve time.

Green Star 1
This Green Star is located on the Yoshi House Planet, circle around Yoshi's House till spoting it. It is suspended in mid-air so Mario/Luigi will either have to backflip, double-jump or side-somersault to reach it.

Alternatively Mario/Luigi can jump into the green pipe to the bottom side of the planet, destroy the crystal and jump into the hole and exit out on top of Yoshi's House. From there Mario/Luigi can walk of the edge to retrieve the Star.

Green Star 2
The second Green Star is located near the Grass Planet, in the abyss beyond the Launch Star. In order to reach it, the player has to have Mario simply jump off the platform with the launch star near it. The star is near the corner of the platform, so it is best to jump off around there. If they jumped correctly, they will land onto the Star before falling into the Black hole. If the player misses it by an inch, they can simply spin for it to obtain it.

Green Star 3
The last Green Star is located on the Sky Fleet Ship over the Warp Pad near the end of the planet. The player must either do a backwards somersault off the Warp Pad and do a wall jump, or stand on the last rotating platform and jump onto the star.

Trivia

 * The Yoshi House Planet appears to be similar to the first planet in the Good Egg Galaxy, as both are the first planets encountered in their respective galaxies, each planet has a bright and dark side, houses are located on the top halves of both planets, and both planets seem to have their top and bottom halves divided exactly in half, access between which is made possible by green Warp Pipes on both planets.
