The Chuffle is a small feline-like predator that tends to live in cold, mountainous forest regions. Its woolly tail grows larger and more luxuriant as it grows up, and it can use this tail to keep itself warm even in the coldest weather. Despite looking heavy and hard to hold up, the wool is in fact lightweight and rain repellent as well as being more insulating against the cold than any other type of natural fiber known, and it is sought after by humans for weaving into clothing.

Chuffles grow long canines that they use to kill their prey in one swift, effective bite. This allows them to kill prey as large as and sometimes larger than themselves. These canine teeth do not reach their full size until the chuffle is fully grown.
