The Haunty Halls Galaxy is a galaxy in the game Super Mario Galaxy 2. It is featured in World 3: The Far Reaches Of The Universe. Like its predecessor, the Ghostly Galaxy from Super Mario Galaxy, it has a ghostly theme. The planets are shaped as hallways full of many enemies including Boos. This galaxy is the debut of a new type of power-up known as the Bulb Berry, a yellow fruit that Yoshi can eat to transform into Bulb Yoshi. This power-up allows Mario to see invisible platforms.

Moving Platform Planet
This planet has platforms moving into a wall. It is the second-longest planet. As its alternative name implies, the platforms disappear into the walls it has. There are a number of hallways on this planet to walk through until Mario finally reaches a Launch Star. There is a teleporter, a Warp Pipe and a checkpoint flag.
Hidden Halls Planet
This planet starts with a visible floor with a Yoshi Egg and a Bulb Berry. Bulb Yoshi must be used in order to progress. There are a number of Bulb Berries scattered around the planet. There is also a door blocking the way and the only way to open it is to find a key. There are a number of enemies on this planet, including Octoboos and Smeeches.
Creepy Corridor Planets
This area is based off a typical haunted house. It is featured in Mission 2: Sneaking Down The Creepy Corridor. The largest planet in the area is reused in the Clone Comet mission. Mattermouth resides here, eating platforms in his way.
