A non-sentient species of flying serpent lived on the Forest Moon of Endor, and at least one specimen lived in a cave. The creature had two small wings slightly forward of the midpoint of its body, and black eyebrows situated above yellow eyes with black pupils. Mostly a single shade of purple, but with a paler snout and spots on its wings, the creature had a forked tongue and four fangs. Its body, which was long and flexible, sported a rattle at the end, and its head featured several spikes. In 3 ABY, the Ewoks Weechee Warrick, Widdle Warrick, Paploo, and Teebo frightened one such serpent when they passed through its cave on their way to the Tree of Light.
