The Croc Fortress has one of the finest smithies in CHIMA. Well, it's not pretty as such, but the blacksmith, Cranvil the Croc is highly respected. He's an expert in weapons made from metals and rocks found in and around the swamps. The dark metals have special magnetic qualities and can be used to craft, rebuild and customize any weapon. Crug likes this one because the shape reminds him of his favorite snack.
