Not much is know about the elusive Spy crab except that he sometimes appears when regular Spys stop being complete ass holes and bend their arms behind their heads and crouch showing them as crab walking. They have their P.D.A out looking up they are very rare and not supposed to be shot at unless they attack you first. Saxton Hale the C.E.O of Mann Co. thinks they are cute and possibly related to the waddaling Scout, turtle Heavy, and the humping Sniper. Not much is know about the other three on the consoles so please support the player that do.
