This sped-up video shows mushroom corals digging themselves out after becoming buried in the sand.

The corals are solitary creatures that move about in the benthic zone of the ocean. This zone is where several organisms live either attached or very close to the ocean floor. These coral are capable of moving in the benthic zone by puffing themselves up and shaking off any sand. Scientists say a coral can excavate itself from a layer of sand within a few hours.
