Curly-tailed blue nose

A curly-tailed blue nose is a Spirit World creature resembling a primate. Since Aang recognized it when he was in the Spirit World, it is possible they also exist in one of the four nations.

History
When Aang was looking for Koh in the Spirit World, he heard a sound which he discovered came from a curly-tailed blue nose near the entrance to Koh's Lair. After the blue nose turned around, he realized that its face had been stolen.

Anatomy
The curly-tailed blue nose has very long, sharp fangs and yellow beady eyes. It has an elongated muzzle with distinctive characteristics such as a red stripe down the middle and protruding blue ridges on the sides. Although the rest of the body is coated with brown fur, his face is covered with white fur. His exceptionally long tail is always curled, hence his name.

Connection
This animal is closely related to the mandrill, world's largest species of monkey.

Trivia

 * Although his name suggests that his nose would be blue, it is in fact red, much like the nose of the mandrill.
 * One of Koh's faces that was seen when he showed it to Aang to make him fear, is probably the face that was stolen from this creature.
