Human: Please generate a brief description of a spooky cave in the wilderness with tunnels, a roa'ter, and stones. Assistant: 
The well-lit tunnel slopes down towards a thick, clear glaes wall. Hard-packed earth, littered with large stones fills most of the space on the other side of the barrier. Enormous tunnels butt right up against the viewing surface, offering a look at a juvenile roa'ter in its underground home.
