Boo Moon Galaxy

Boo Moon Galaxy is a galaxy in the game Super Mario Galaxy 2. 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. The level also has poisonous water that will instantly kill Mario if he lands in it. Snake Blocks are found throughout the level. The Boo Mushroom which turns Mario into Boo Mario is first found in this galaxy. Common enemies include Octoboos and Boos.

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 kill 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. It is only accessible after completing the first mission.

Bonus Planet
This planet can be accessible via the Warp Pad on the first planet. It is inhabited by Pumpkinhead Goombas. If Mario defeats all of them within time limit, he'll get three Life Mushrooms.

Swamp Planet
This planet has a serie of Snake Blocks. If Mario steps on those, they'll start moving and Mario has to follow their moves or else he'll fall. These Blocks will lead Mario into the Launch Star and a hidden star. Octoboos inhabit this planet. Also, a ? Coin and a Comet Medal are found on it.

The Moon
The Moon in this galaxy will balance if Mario steps on it. And possibly make him fall in space when he stands on one of its sides too long. There are five Launch Star pieces on it that the plumber needs to collect and form a Launch Star.

Graveyard Planet
When Mario first lands on this planet, he'll see it's a gray platform with graves drawing 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 the Boos.

Silver Stars Pop-Up
To get this Power Star, Mario must first make his way to the Graveyard Planet. To do so, he should find the Launch Star in the first planet and fly to the next one. Here, he has to use the pink moving blocks to process. The Launch Star is located near the roof. When he uses it, he'll end up on the Moon. The only thing he has to do here is to get all the Launch Star pieces and fly to the final planet.

On this planet, Mario must collect all the Silver Stars. Only two of them can be collected at the first time, but he can reach the others after activating the switch and using the graves. When all the Silver Star are collected, they'll transform into a Power Star.

Haunting the Howling Tower

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.
