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 area with a potlight 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.

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.

Pink Blocks Planet
This planet has a serie of moving pink 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. 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.
