A sewer is an underground place, usually under cities, with pipes, sludge, Sewer Trolls, fungus, and the like.

List of SewersEdit

Effects on monstersEdit

Trolls seem to gain power from living in sewers, while Giants don't do as well as those on the surface. Snakes, bats and rats don't seem to be affected at all. Lava Fungus is more powerful than Sewer Fungus, but that may just be an effect of the Lava.


Oakland Sewer was the original sewer. If an old article says "the sewer," it is referring to this one.

Butler Sewer was the old name for the Castle Sewer, before the Castle fully connected to it.
