The Boiler Room is an underground room below the Night Club. Located here is a large filing cabinet, which hosts the past 6 old issues of the Club Penguin Times. The Boiler Room can be accessed by climbing down from a fake speaker in the Night Club, or from a door on the left side of the Underground Pool.
During the April Fools Party 2017, in place of the boiler was a frying pan. Above it was a caution sign saying "Caution: Hot."
At the Medieval Party 2017, the room was fully decorated. The boiler was redesigned to look more medieval; above it was a sign saying: "The Smithy". There were tools such as a jackhammer and wooden hammer hanging up on the wall.
At the Halloween Party 2017, the room was darkened, with pumpkin lights hung from the ceiling. The boiler also leaked green slime instead of water.
During the Christmas Party 2017, a huge Christmas tree was placed in front of the door to the Underground Pool. The crates were also wrapped with bows, and part of the room was replaced by a diamond cave with an entrance that replaced the door.
For the 50th Newspaper Event, greyish balloons and bunting were hung in the room, with a huge banner reading: "50th Newspaper!"
