Silooth
this normally docile creature, no larger than a womp rat, was altered by the ancient Sith alchemists to become a huge, ferocious predator. Its eight legs were strengthened and given huge talons, and its skin was altered to become covered with chitinous, armor plates. Its huge jaws gnashed as it moved, biting and consuming anything in its path. Although these creatures had excellent night-vision, the average silooth could only see things within ten meters of its location. Once it located prey, however, the silooth attacked furiously, and could actually spit acid in a wide spray in an effort to bring down its prey. This acid is stored within the creature in two separate sacs, and was inert until mixed and expelled.
