|Normal Ghosts||Some Greenies|
When first entering the Garage you will see E. Gadd's car in the middle of the room. If you check it, you will get the Poltergust 5000 in mission A-1 Poltergust 5000. You will find the key need to progress in the chest to left side of the room. After getting the key, you will head to the door where a regular ghost will appear in the car, which is followed by a second regular ghost. Once the room is cleared you can then progress to the next room.
The Garage is one of the first areas in Luigi's Mansion 2. In it is random junk with a old fashion car in the very middle. There's also a chest with a key in the left corner of the room. There are also Boxes in the room which contain coins in the the bottom corners.

Two greenies appear in a cutscene but no fighting occurs in the Garage.
