Yak

Yaks are the species of bovine that live in every part of Narnia. Yaks are loyal to Aslan and would do anything what is right.

The Lion, the Witch and the Wardrobe and Prince Caspian (4D Version)
The yaks appear in the 4D experience of the first film where they fight with the rhinos against the moose.

The moose, rhinos, and yaks are seen with the old Narnians ready to fight Miraz.
