Unidentified flying serpent

A flying serpent lived in a cave on the Forest Moon of Endor. It had two small wings, a forked tongue, and black eyebrows situated above yellow eyes with black pupils. Its purple body, which was long and flexible, held a rattle at the end. In 3 ABY, the Ewoks Weechee Warrick, Widdle Warrick, Paploo, and Teebo frightened the creature when they passed through the cave on their way to the Tree of Light.

Behind the scenes
The flying serpent first appears in "The Tree of Light," the sixth episode of the first season of the Star Wars: Ewoks television series. "The Tree of Light," written by Bob Carrau and directed by Raymond Jafelice, first aired on October 12, 1985.
