A flying serpent, a species lacking sentience, inhabited the Forest Moon of Endor, with at least one individual residing within an unidentified Endor cave. This creature possessed a pair of diminutive wings positioned slightly ahead of its body's center, and black eyebrows above its yellow eyes that featured black pupils. Predominantly purple in color, it displayed a lighter-toned snout and spotted wings, along with a forked tongue and four fangs. The serpent's elongated, pliable body concluded with a rattle, and its head was adorned with multiple spikes. During 3 ABY, Ewoks including Weechee Warrick, Widdle Warrick, Paploo, as well as Teebo startled a serpent of this type as they journeyed through its cave en route to the Tree of Light.
The animated Star Wars Legends show Ewoks introduced the flying serpent in "The Tree of Light," the sixth episode of its first season. This episode was initially broadcast on October 12, 1985.
