Barnacle Goblins

Also called thieves because they steal the fish the Mangdol Whales have gathered. The Giant Marsh Worms they breed have the ability to freely alter their body's and mouth's shape. Using their mouths they are able to dig through the thin crust of the pit to reach the waters of the wine glass where they use their mouths to suck up the fish. Latter the Barnacle goblins take the fish from their stomach.
