Boo Moon Galaxy

Boo Moon Galaxy is a galaxy in the game Super Mario Galaxy 2 for the Wii. It is located in World 5. The level is a stereotypical haunted mansion themed galaxy. The starting planet is completely pitch black and requires some patience to reach the Launch Star. Its name is a pun on the phrase "blue moon". The level also has poisonous water that will make Mario or Luigi lose a life instantly. Snake Blocks are found throughout the level. This is the only galaxy to involve use of the Boo Mushroom. Common enemies include Octoboos and Boos.

There are no Prankster Comets for this galaxy, until the Green Stars are unlocked.

Planets
NOTE: Unless otherwise noted, all names are unofficial.

Starting Planet
The starting planet is a dark maze with a spotlight on Mario. It is full of Boos that chase Mario and try to harm him. This planet has also a Warp Pad leading to a Bonus Planet. The Launch Star is found at the end of this planet. This planet also has a Warp Pipe which leads into an underground tower and is only accessible after completing the first mission. There are some pictures of Boos and 1-Up Mushrooms in the walls. The doors that open when Mario approaches them make the same sound as the Super Mario World doors.

Bonus Planet
This planet can be accessible via the Teleporter on the first planet. It is inhabited by Jack O' Goombas. If Mario defeats all of them within the time limit, he'll get three 1-Up Mushrooms.

Swamp Planet
This planet has a series of Snake Blocks. If Mario steps on those, they'll start moving and Mario has to use them to progress, and if he falls back he'll fall into the poison swamp and will die instantly. These Blocks will lead Mario into the Launch Star and a hidden star. Octoboos inhabit this planet and block Mario's path. A ? Coin present on the planet will make music notes appear which will make three 1-Up Mushrooms appear if Mario collects all of them. A Comet Medal and a secret Power Star are also found on this planet. This planet is similar to a book, as it will fold when Mario steps on certain platforms.

The Moon
The Moon in this galaxy will balance if Mario steps on it, and possibly make him fall into space when he stands on one of its sides too long. It acts like a see-saw. There are five yellow Star Chips on it that Mario needs to collect in order to form a Launch Star. This planet also appears in the ending credits of the game with a Red Luma, a Blue Luma and a Yellow Luma floating above it.

Graveyard Planet
When Mario first lands on this planet, he'll see it's a giant book with grave drawings on it. But when he activates the switch, a wall will raise revealing the three graves in 3D. Mario can jump on those to collect Silver Stars, Life Mushrooms and coins. The enemies encountered here are Boos. This planet is a pop-up book. When the player hits the ground pound switch a ticking noise will play and even when the pop-up book descends.

Howling Tower Planet
A tall, sidescroller planet. This is the only place in the game where Mario can find the Boo Mushroom to turn into Boo Mario. The most common enemies here are Octoboos, who will try to make Mario fall and lose his power-up. There are also fans in here. At the top of the tower is the Power Star.

Silver Stars Pop-Up
Mario will begin the level on the darkened Starting Planet. He must walk through the door in the room he appears in, and go to the left to find another corridor. Mario must go follow this corridor around a corner to the Launch Star, which will take Mario to the Swamp Planet. There, he must step on the Snake Blocks to activate them, which will lead the player to a platform with a coin and a Checkpoint Flag.

Mario must now step on the second set of Snake Blocks here to further progress through the planet. These Snake Blocks will eventually lead to the Comet Medal and the next Launch Star, which Mario can take to the Moon. Once on the Moon, Mario must collect all of the Star Chips floating in the air above it. This will create the next Launch Star, which will appear to the right of the Moon, and will take Mario to the Graveyard Planet and another Checkpoint Flag.

On this planet, Mario must collect all five Silver Stars. Two of them are on the ground and can be collected right away, but the other three must be reached by activating the Ground Pound switch to raise several pop-up portions of the planet. Mario must now jump onto the pop-up tombstones to reach the three remaining Silver Stars. When all five of the Silver Stars have been collected, they will transform into a Power Star.

Haunting the Howling Tower
When Mario completes the first mission, a new path will be revealed on the Starting Planet. Mario can follow it to get to the green Warp Pipe. When he uses it, he'll get to an underground haunted tower. Mario has to use the Boo Mushroom to transform into his Ghost Form to go through walls and float in the air. Boo Mario must make his way to the top by avoiding the enemies and getting Boo Mushrooms so he can grab the Power Star located there.
