White hamster

The White Hamster is a small, quadruped mammal found throughout the world. It was first seen in "The Boy in the Iceberg", scurrying through an abandoned Fire Navy ship near the Southern Water Tribe.

Anatomy
While it still squeaks in the same tone as a typical rat and is about the same size, the White Hamster also shares many characteristics to the real life house cat. For one, its tail is long like a cat's, although mostly flat, and it has a triangular head with cat-like ears.

Connection
These little creatures seem most connected to real life hamsters and domestic cats. Hamsters are small, four-legged, omnivorous rodents that are often kept as pets.
