The Sewer Cell is a room in Granny that was added in Version 1.7 along with the other rooms in the new area. It is located in the Cellar Swamp other to the staircase going up to the Crow Room.
This room is initially locked by a Red Switch on the door and this requires the Player to go to a Small Window at the side of the room and use a Tranquilizer Dart or Shotgun to shoot it. When hit, the door will unlock.
The room has the same color scheme as the rest of the swamp and includes a small table which always contains the Freeze Trap on it. There will always be a useful item in this room.
At the corner of the room, a Skeleton is found, and its skull will come off if the Player goes too close. There are rumors that it could be the previous victim.
