Lumberer

The lumberer is a species of herbivorous mammal that was originally native to Asia, but has since been introduced to most of the Old World (Eurasia, Africa, Australia, and New Zealand) and New World (North America and South America), except Antarctica and the Arctic. Despite their resemblance to hippopotamuses or hornless rhinoceroses, they are only distantly related, and aren't even members of the hoofed mammals, this is because it is a result of convergent evolution. These herbivores can feed on almost every kind of plant matter on Earth with no known side effects, making it the most adaptable herbivorous large mammal alive today. They also have a fast reproductive system so they can breed really fast, around 2-4 weeks after mating, and very frequently.
