Here we got the Warrens. Yo baby, gimme some lovin' cause this place looks like it was made for some!
This "underground" structure is covered in/coated with/made from/carved from the Durafoam which coats everything in Bottomwarp's main plaza. Its design speaks of sex, from the rounded vulval mound of its entrance, to the big foam plug in its "back door".
Once inside the heart of the Warrens, take a left and head deeper inside to find the Creche, a place for Bottomwarpers and their friends to sleep in social comfort. It's dark, lit only by strings of gaily colored LEDs and the occasional lit-up being. The temperature is best suited for snuggling and sleeping with others in the pockets, bunks, and hammocks which line the walls and are strung across the open space within.
