Haunty Halls Galaxy

Haunty Halls Galaxy is a galaxy in World 3 in Super Mario Galaxy 2. This is the first galaxy to feature the Bulb Berry. In this galaxy, new enemies are found including Octoboos, and Mattermouths. There's also a passage which has Big Boos, and floors which are eaten by the Mattermouths. As the name implies, this galaxy is composed of smaller planetoids shaped like mansion halls with different features each.

Starting Planet
This planet is a long, curved hallway leading to a Launch Star. The player will encounter a few Octoboos moving in a circular pattern. The planet has three ? Blocks and a Teleporter. During the second mission, the planet will be much longer and form the shape of a semicircle. The player will encounter a Big Boo and four Boos that are larger than usual. The second part of the hallway has some missing pieces and there are also shrinking tiles.

Disappearing Paths Planet
As its name implies, this planet has moving paths that disappear when they come in contact with one of the walls. The player has to cross them carefully while trying to avoid the Octoboos and the gaps in the path. The paths become progressively faster and more oddly shaped as the player progresses through the planet. The Comet Medal is found at the end of this planet. The Warp Pipe at the end takes the player to the Hidden Halls Planet.

Hidden Halls Planet
The majority of this planet is hidden. Only Bulb Yoshi can make the areas appear and cross them. The player will encounter Octoboos and a Smeech on this planet. Many Coin Blocks can be found here. This planet is based on one of the planets found in the Matter Splatter Mansion level from the Ghostly Galaxy in Super Mario Galaxy, which it very closely resembles. The Power Star is located at the end of this planet, on top of a bookshelf.

Creepy Corridor Planet
This planet begins with the player landing on a platform with a Boo on it. The player will need to travel across the planet while avoiding the Boos. At the end, they will come across a Sling Star, which will take them to the main part of the planet. There will be Checkpoint Flag and a conveyor belt-like pathway that moves in the direction opposite of the way to the Power Star. The platform has some Boos and Mattermouths eating away at it. After that pathway has been crossed, there will be another platform followed by a curved conveyor belt-like path that also with Mattermouths eating away at it. On the final platform, the Big Boo and the four Boos appear again and will chase the player down a path of moving platforms and some Shrinking Tiles to the Power Star.
