Glop Monsters are fearsome, serpentine organisms on the forest moon of Endor. They infest the local glop pits, attacking intruders that encroach into their territory. Normally, they sleep buried in the glop pit soil, but will hostilely erupt out of the dirt when disturbed. Despite their ferocious appearances, they appear to have sensitive skin - likely a cause and effect of their apparent sensitivity to ground vibrations - which makes them especially susceptible to skin-affecting weapons such as itching powders.
