Glok monsters were serpent-like beings originating from the forest moon of Endor, specifically the glop pits. These creatures, resembling snakes, were territorial and would lash out at anyone who dared to trespass within their domain. Glok monsters typically slumbered beneath the earth, bursting forth from the soil to ambush their prey. During his campaign, the stranger once harnessed the Sunstar's energy to command a glok monster. This controlled monster managed to seize the Ewok child Latara, but was subsequently confronted by Teebo, who deployed a potion of itching powder against it.
