Cells of the successful.
This is where the Test subjects who have managed to survive the entire process of becoming a strange hybrid of species spend their nights. The walls are painfully white, no decoration what-so-ever. The only color you'll find on the floor is red, from the blood of the Test subjects. When they misbehave, and after their brutal punishments they are sent to their cells. These cells' main walls are see through and made of a substance impossible to get through. They are the about two or three rooms big. A bedroom, bathroom, and small living room. The only color you will find in here is white, and all the furniture is securely bolted and welded to the floor. Some cells hold roommates but usually they are for one subject each. Only well behaved test subjects get roommates, there are cameras in every room except for the bathrooms, and every room is bugged, so they know everything you say...
