Ghostly Galaxy

The Ghostly Galaxy is a galaxy in Super Mario Galaxy where Mario turns into a Boo with his new Boo Suit. Pink Boos, UFO spinning tops with Bob-ombs on them, Swoopers, Cosmic Scuttle Bugs, and Pumpkin Heads have been spotted in screenshots. Recent gameplay footage has shown Luigi in a jail cell and calling out for Mario in on a haunted house planet.

Luigi and the Haunted Mansion
At first, Mario starts off on the Shroom Brigade's ship, but he'll have to use a Launch Star to reach the pathway into the mansion. Pumpkin Goombas litter the pathway, so Mario must be careful. Boos are inside the mansion, but there's a beam of light swinging around, so Mario has to lure them into the light to defeat them and get the items they were guarding. One of the Boos had a key to get deeper into the mansion.

Soon, there are Star Chips to collect to rebuild a Launch Star which will then be located in one of the windows a black hole was. using the Launch Star, Mario is then launched into another part of the mansion, where Luigi is calling for help, but the window makes it impossible to escape from. Mario will have to find another way inside, where he discovers a new power-up, the Boo Mushroom. As Boo Mario, he needs to vanish to pass through the bars, but must be careful as a beam of light is in the next area. A Boo falls in love with Mario somehow, so he'll have to get into the last room Luigi's in. Mario will need to return to normal before he can speak with Luigi and get the Power Star.

A Very Spooky Sprint
In this level, Mario must blast to the edge of the galaxy and race the Spooky Speedster, using paths of Pull Stars.

Matter Splatter Mansion
A mission similar to the Matter Splatter Galaxy. Platforms, and rooms only exist when a sort of "Spot Light" comes over them. The Player will need to go through, getting keys, and unlocking doors to get through, Until, eventually, there will be a Power Star behind one of the door.s
