Glok monsters were snake-like creatures on the forest moon of Endor. They were native to the glop pits and attacked intruders into their area. Glok monsters took to sleeping under the ground and would "erupt" out of the dirt when attacking. The stranger once used the power of the Sunstar to control a glok monster in his campaign against the Ewoks. The monster was able to capture the Ewok child Latara before being accosted by Teebo with a potion of itching powder.
