The Sewers is a location in Stardew Valley. Located south of Pelican Town in Cindersap Forest, the Sewers is initially inaccessible. To gain access, the player must receive the Rusty Key, an item that is rewarded by Gunther after donating 60 items to the museum, and unlock the sewers from town or near Marnie's Ranch.
Krobus resides within the eastern portion of the sewer.
