The sewer is the stag's lair that is seen in "No One Can Hear You." The Stag imprisoned the Candy People in the sewer by sticking them to the wall with his sticky saliva. The sewer is filled with tools and a significant amount of plumbing and pipes, mostly covered in Stag's saliva. There are many chambers that are offshoots to the main chamber, but they are not explored. The walls have a lot of stains. In the middle of the main chamber, there is a giant whirlpool with many pipes emptying into it. When Stag was knocked out, the Candy People disposed of him by pushing his unconscious body into the whirlpool.
