Salty crablets can only be found on Uncharted Isles in the Arc region in groups of 6 crablets. Despite being a creature, the crystal deposit on the crablets back acts as a mining resource. Mining the deposit requires level 91 Mining, and yields sea salt, sought after as an ingredient in arc gumbo. The salts may also be sold to Salty Goods in the Waiko market for 4 chimes each.
