Berriegolper

The berriegolper split from its ancestor, the monofoot, and moved to Darwin Boreal. In this cold and desolate land, unlike its ancestor's temperate home, it is much harder to stay warm. The berriegolper became a seasonal herbivore, sleeping in warm burrows dug into the snow and dirt for most of the year, and going outside only at the spring and short summer days. To keep itself further warm in the cold days of winter and autumn, the berriegolper lives with an enlarged family of 50 individuals, all cousins up to second degree, inside the burrows.

It relies on berries and roots for its food, mainly of the solar carnofern's, and has grown smaller than its ancestor as a result. The color of its hide changed to resemble the yellow mud and black flora of its summer habitat, and the skin surrounding its jaws became leathery and hard, to be able to grab the sunstalk better and draw it out of the soil. One of its fingers grew longer, and is used to dig small trenches around the sunstalk's base, to help it succeed in drawing out the flora. Because the sunstalk is as big as the berriegolper, individuals will sometimes cooperate in felling down these flora.

The females have an eye patch with a darker shade of blue than that of the males, and it grows darker with age. The matriarchs of the herd will sometimes have totally black eye patches.

During mating season, the males will make long and strong calls, similar to a howling, to attract female partners. After a while, these creatures developed an air sack on their back, to help store air for the howling call. This air sack also helps with breathing, allowing more oxygen to enter the body.
