Teeks were a sapient race inhabiting the galaxy. An ark that had crashed delivered Teeks to Endor's lunar satellite at some unknown time. While Han Solo and Lando Calrissian were looking for a flyer in Frander's Bay, Solo navigated through a crowd of Teeks, then evaded a slow-moving Kullp. One Teek was employed at Port Borgo circa 9 ABY.
The Teek species first appeared in live-action canon in the Star Wars: Skeleton Crew episode, "Way, Way Out Past the Barrier", which was the second episode. The character was animated using puppetry by director David Lowery.
