A serpentine dragon with a long neck and tail. Adapted for life in the swamps and marshes, its coloring reflects the vegetation it likes to hide in, waiting to ambush unsuspecting victims. It has two somewhat large fangs that it uses to inject venom, similar to a snake. This dragon has four limbs, each with three clawed toes. It also has two horns on top of its head.
