Horned Kangaroo

A horned kangaroo is a mutated version of the kangaroo, an Australian marsupial. It is not certain how they ended up in North America, though it is possible that they have escaped from a zoo.

Characteristics
Kangaroos are large marsupials, and have large, powerful hind legs, large feet designed for leaping, and long muscular tail for balance; as well as a distinctly small head. The kangaroos found in the wasteland are mutated, and have developed horns. The status of kangaroos in the wasteland is unknown.

Appearances
The remains of a horned kangaroo appear in both Fallout and Fallout 2. There are no alive kangaroos though and remains may actually belong to another creature (game characters just think that these bones look like Horned Kangaroo but not sure if they really are).
