The Thiwn-Horned Shnorm is a large herbivore native to the southern grasslands of the Eruth Continent. It is a close relative of the Shnormalope and Golden Shnorm. Like the former, it has a pair of long, ceratinous horns which are primarily used for combat. With these formidable weapons on hand, few predators dare to tackle this walking mountain of flesh and muscle. And like its golden relative, it has a prominent mane and dewlap, which make it more difficult for predators to deliver a fatal bite to the neck. The latter facilitates temperature regulation by offering a broad, flat surface for heat dissipation.

Twin-Horned Shnorms lead solitary lives. Each individual spends most of their days searching for fresh leaves and grass. It can handle tougher foliage better than the Golden Shnorm because of its stronger teeth and trunk. If given the choice, this beast will go for more delicate leaves and grass, but in times of hardship, it can even survive off of thorny bramble bushes.

Shnorms rarely interact with members of their own species. Only during the mating season, which occurs at the peak of the rainy season, do they look for company. Males with longer horns and greater size have a higher chance of attracting a mate.

Twin-Horned Shnorms also have a fairly elaborate mating ritual. Once a male has found a female who is receptive, the two will engage in a kind of "jousting match" in which they will snort together, softly interlock their horns, and bob their heads up and down. If the male manages to stay in synch with the female's movements, they will then mate.

After a 10-month pregnancy, the female will give birth to 1 offspring, which she will raise for around 3 years before chasing it off and seeking out a mate during the next rainy season.
