Players may find a pool of quicksand with the peasant with his legs bitten off in the middle. When players approach, Monstrous Dune Thresher drags the screaming peasant underground, emerging afterwards.
It has Extra Health and Electrified affixes, and in addition, has much higher damage than other unique Sand Sharks. However, while unburrowed, it moves and attacks much slower than any other Dune Thresher. Visually, it is the largest Sand Shark in game.
