The Sewer Tunnel is a tunnel in Granny's house, which was added in Version 1.7.


It is a fairly dark and narrow tunnel. Being located in the Cellar Swamp, it is flooded with shallow water and the ground and walls have a lot of paint/dust blots on them. Much like the Secret Tunnel, Hidden Tunnel, and Attic Tunnel, Granny is not able to access this tunnel, which makes it a possible hiding place for the Player. It is coated with a thick layer of moss and mold.

Getting In

There are two ways for the player to access the sewer tunnel:

  1. The player can drop down from the Backyard drain and access it from there.
  2. The player can go the long way and access it by passing the Meat Room, Old Storage Room, and Crow Room.

Item Spawning

  • The Padlock Code can rarely spawn on the wall just before the tunnel.


  • There is a major glitch that will cause you to go off of the map. Throw the vase at the bottom of the tunnel while hugging the wall farthest from the Sewer Cell and drop the grey vase downwards. Stand up. You are now off of the map, and you can sneak to other places in Granny's House (ie. Well)
