A tar beast is a mud elemental, made of water and earth. It is a creature draped with green moss and oozes in order to move across the ground. Its hide appears slick, taut, and rubbery, and the creature forms and retracts small pseudopods as it moves. Any face it might possess is hidden under the moss. Tar beasts begin combat by hurling blobs at their nearest foes. When an enemy closes in, the tar beast engages that enemy only until it becomes stuck in the tar creature's adhesive skin. The tar beast then shifts its focus to the next-closest enemy.
