Human: Please generate a detailed description of a spooky scene outside of a sea cave with scratches on the wall. Assistant: 
A salty sea breeze moans loudly through a series of porous holes in sections of the tunnel's walls. Somewhere further within the earthen tomb come the scuttling echoes of movement, though discerning any details about what the source may be is impossible through the moaning sea air. Four sets of four deep scratches mar an area of sandstone on one wall, as if some creature had pounced off of it in a hasty pursuit or retreat.
