The guards grimace at Tsal and whine, "Oh, come on now! Get that mutt out of here. It's going to smell like piss for weeks!"
They open the locked door to the guard house and allow you entrance into the prison, while the four human guards walk to where Tsal urinated and begin to argue over who is on cleaning duty. You walk another forty feet down a corridor and past a sentry post guarded by four bored goblins who snicker at the whining humans as you pass.
Another 120 feet down the hallway and you come to a small chamber, about 20 feet wide and 30 feet to the north-south direction. Inside are four bugbears who smile wickedly at the prisoners. "Ah, what have we here? Men, you can leave your prisoners, since we can take care of them now. Perhaps you left something valuable on these," the bugbears suggest with a smile as they move forward to search Kaeso and the others.
