Flarthogs are a species of wandering, burrowing creatures that look like tiny pink hedgehogs with giant ears. They have no concept of personal property and will take whatever they want from each other or people's homes, though once they have an object, they usually carry it around with them everywhere. Each flarthog has a unique personality, and some are known to be very aggressive. Their only source of food is a slimy bacterial organism that they grow on the underside of their quills, which commonly leads to bouts of cannibalism in some areas.
