Billy-Bumblers, also known simply as bumblers or throcken (which is also the term used for a group of bumblers), are creatures with black and grey striped fur, spiral tails, and gold-ringed eyes. They look like a cross between raccoons, woodchucks, and dachshunds.
Bumblers are much more intelligent than canines and were used to herd sheep before the world moved on. Others were bred to hunt the Grandfather fleas. They also had stayed in barony castle. They have the ability to mimic what they hear, though they have trouble with pronunciation. Billy-Bumblers are particularly sensitive to the approach of a Starkblast, and will face north when one is coming. They are also well known for their friendliness, even in the wild.
