Koalaotter

History
The Koalaotter is a furry, aquatic mammal who enjoys backstroking through icy waters. The creature has rounded ears, a black nose, and small black eyes. It has large furry ears, four legs and a wide, flat tail. The Koalaotter's back and head are light gray while its underbelly is white. First seen in the frozen waters of the North Pole, the Koalaotter likes to lazily backstroke in the frozen water using its tail.

A Koloaotter is seen in "The Waterbending Master."

Connection
The face of the Koalaotter is taken almost entirely from the koala, a marsupial native to Australia. The rest of the Koalaotter's body closely resembles a sea otter, though the principal connection to the sea otter seems to be the creature's preference for the backstroke and its playful demeanor.
