Buffalo yak

The buffalo yak is one of the Northern Water Tribe's main forms of transportation.

Anatomy
The buffalo yak is a large, gray and white animal that has four muscular legs that end in hooves. Its head is crowned with a pair of horns that emerge sideways from the forehead and then curve backward. The creature's body ends in a small, furry tail. Its shaggy fur is gray on its back while white in a patch around its eyes, on its neck, and on its underbelly.

Connection
The horns of this creature suggest a link to the real life water buffalo or perhaps the yak, a type of mountain bovine. The most striking feature of the males of this species is the large pair of horns that emerge sideways from its forehead and then curve backward. The buffalo yak's "bell bottomed" feet suggest a connection to the Clydesdale horse. This animal is distinguished not only for its size, but for the bell bottoms of hair, called feathers, around its feet.

Tamed behavior
The buffalo yak is native to the North Pole and is an extremely useful animal to the people at the Northern Water Tribe. Bred for many years as a domestic animal, this docile creature is a lot like our version of a horse, used for transportation and to carry supplies. Because it can survive even in the coldest temperatures, the buffalo yak is the perfect animal to take on long hunting trips into the frozen tundra.
