Human: Make a spooky scene inside of a cave passage with a bone. Assistant: 
Sometime in the distant past, this passageway was wider. A huge slab of rock has forced its way up from beneath like a stony wedge, narrowing the path almost to uselessness. Occasional bits of bone litter the cracked and fissured ground. The air is curiously damp, enough so that the walls are covered with a thick fur of moss or mold that gives off a musty stench like rotting leather mixed with rancid butter.
