Yugul is a large horned caterpillar. Very large to tell the truth: adult animals (if they were not eaten earlier) grow up to one and a half meter in length and reach a centner of weight. Their thick body is covered with yellow platelets, and the head is topped with a crown of branched horns. Unfortunately, yuguls are edible and very sluggish, so their population is not large. They live only in the Wild Lands and Borderlands; although there are many savages there, the density of the population is very low, that allows the caterpillars to survive and reproduce. Meat of the caterpillar is not very tasty, but very nutritious; and horns are highly valued by the shamans of the primates.
