The swamp is a dirty sewer area of the house that the Player can access from going down the one-way drain in the Backyard next to the Playhouse. They will fall into a small room and then they will approach the Swamp Tunnel that will lead them to the main area. There is a staircase opposite the Classified Room which leads up to the Crow Room.
- Granny can access this area, with the exception of the Cellar Swamp Entrance and the Sewer Tunnel so the Player should be cautious as dropping items here still makes noise.
- It is weird that the water isn't replaced with blood in Nightmare mode.
