Badgerfrog

The badgerfrog is a chimerical, furry, hopping animal that is indigenous to the Western Air Temple.

History
The badgerfrog was first seen when Zuko practiced his introduction to the Avatar's group. One particular badgerfrog seemed to be friendly to Zuko and lived at his campsite. However, it was not seen again after Zuko joined Aang's group.

While on a rescue mission with Sokka, Zuko instructed Aang in a letter to do a series of exercises every time he heard a badgerfrog croak while he was gone.

Anatomy
The badgerfrog seen at Zuko's camp was mostly brown with a green underside. It had white markings on the top of its head running down its back and along its limbs and muzzle. Its forefeet had four toes each while its hind feet each had four long, sharp claws. Its eyes were a yellow-green color, with odd cross-shaped pupils.

Connection
The badgerfrog is a combination of two real-world animals, namely the badger and the bull frog.

Behavior
At first look, the badgerfrog seems cute and harmless, but if cornered by a predator, it will defend itself by hopping, clawing, and biting angrily. Badgerfrogs seem to enjoy sounds, and they may stay at a certain spot if it knows it will be hearing speech or conversation. It was stated by Avatar Extras that badgerfrogs croak every two minutes.
