Cold Storage (Japanese: 冷凍室 Freezer) is a room in Area Four of Luigi's Mansion. Here, Luigi fights Sir Weston. After Luigi defeats Sir Weston, he receives the Key to The Artist's Studio.
Cold Storage is a plain room with a few points of interest. There are four frozen crates and two frozen shelves throughout the room and a small campsite where Sir Weston sleeps. One notable thing is that the entire floor is covered in ice, giving less traction on the ground than in other rooms. The ceiling is covered with stalactites that deal a massive twenty damage if they fall on Luigi.
