Honeyed Pasture Take every chance you dare

Mason was getting a bit worried that his companion would end up being the loser in this battle. At his suggestion, Hush was now trying to pick the moving-rock up but it was having none of it.
 
Mason pressed his nose in at the creature from the other side between Hush’s lunges. Coming at it from ‘behind’ gave him an element of surprise. He snapped violently at the cracking pincers and his teeth hit a hard yet un-rock-like substance. Mason drew back, licking the salt  now on his lips, and crowed triumphantly when he saw that one of the crab’s pincers had toppled sideways, and was now laying at an awkward angle to the creature. The appendage was still attached but it was useless and unmoving.
 
Mason waited to see whether Hush would have more luck when the thing only had one snapping weapon.
