Crabcavators are amphibious creatures. They are part hermit crab and part excavator. They have six legs: five of them are normal legs similar in appearance to those of a Shockarachnid while the sixth leg is a mining drill similar in appearance to the tail of a Plowasaur and presumably used for the same purpose. They are very reclusive, especially if their shell has been lost or damaged. If this happens, they will look for scrap to weld into a new shell using a welding torch hidden in their larger claw of the two. They are rusty brown in regular light, but in blue-tinted light they appear Stegarbasaur-green.
