Pepper

Pepper is a flying bison owned by Tenzin and his family. He helped to guide Tenzin's children on their quest to locate Avatar Korra.

History
After deciding that he had no better options, Tenzin sent his children off on Pepper to go and find Korra. The three children departed, with Jinora in charge, hoping that by hunting the world and using Jinora's spiritual abilities they would be able to detect her.

After traveling throughout the Earth Kingdom, Pepper and Tenzin's children eventually reach the Foggy Swamp, where they have an abrupt landing and Pepper becomes entangled in vines.
