Typically found in the wastelands Forest regions, beavers are mutated versions of furred pre-War beavers. While maintaining their size, beavers underwent a series of other mutations. The growth of fur has been greatly reduced, revealing wrinkled, fleshy pink skin.

The tail and back are covered in jagged spike growths protruding from the body. The nose and front teeth are remarkably exaggerated. The meat from beavers is a staple amongst tribals in the Zion valley who believe it has healing properties. While beavers dont pose much threat to humans or other Wasteland creatures they can cause serious structural damage knowing through wooden and metal support beams.
