Robber Crab

Historical Background
The robber crab is not an actual animal but the nickname of the coconut crab. It gets the robber crab name due to the the belief it often steals shiny, metallic objects from tents. It is currently the largest living land arthropod in the world. Interestingly enough the crab has a blueish-color to its shell, much like its FFXI version and may match its power; the claw pressure from a coconut crab can bend metal, which has been problematic when they are kept as pets due to them escaping from their cages.
