Vonnegut Quillmow

The Vonnegut Quillmow split from its ancestor the Quillmow. Its quills only grow on its butt and are much thinner. It has grown much larger and has taken the niche of Earth grizzly bears. It is an opportunistic omnivore. It is not a picky eater and will try just about anything once. Like its ancestor it has a pig-like snout that can help it find food even underground. It will use its powerful claws to dig up food or break open rotten logs. Even xenobee hives are not off limits from them. Its feet are technically still webbed, much like a polar bear's however they do not swim as much as their ancestor. Their tail is no longer a paddle shape but quill shaped to supplements its butt quill defenses.

The Vonnegut Quillmow no longer create their own shelters but instead will evict fauna from theirs or even sleep in hollowed-out logs. They face their quilled butts at the entrance of the burrow so any predators, such as the Sparkleshrog, will think twice before coming after them when they are sleeping.

The Vonnegut Quillmow are even more solitary than their ancestors and only meet to mate. They no longer fight with their tusks but show off their butt quills like a peacock showing off their plumage. The larger more numerous the male's quills, the more attractive they are to females. Males will fight over territory and sometimes even control their own island. They mostly show mock charges and roar. Sometimes males will use their tusks and claws if the other male won't leave their territory.

After mating, the male will stick around and guard the female, preventing other males from trying to mate with her, though this is not always successful. The male will leave about a week after the joeys are born. The joeys are born fetal and helpless after just two weeks, but take as long as 4 months to develop sufficiently to leave the pouch. Their mother may leave them in a burrow nest, returning to feed them a few times a day. The juveniles become independent at one year of age and are fully grown at two.
