You search the cavern and find other crabs, but these are smaller, about hand sized. The gruesome scene needs no other description other than the fact that a couple legs are unaccounted for.
There are no other exits to the cavern. A small pool is situated near the back of the cave. The cracked crab lies bobbing in it like some grisly Halloween party game.
This may just put you off of crab for a long while.
