Chuug

A chuug is one of few mammals that survive the warmth of the caverns on Grimlahd. It's a pack animal, and literally has a brain the size of a pea. Its body is built like a large yak, but it has very short hair, save a long, dark mohawk-like ridge down the center of the back. On some varieties, the hair is almost non-existent, save for the ridge of hair on its back.
