Dugbog

The Dugbog is a marsh-dwelling magical creature found in Europe and North and South America. It resembles a piece of dead wood while stationary. It has finned paws and sharp teeth, and glides through marshland, feeding on small animals, and occasionally attacking the ankles of humans who venture into its habitat. Its favourite food is the Mandrake, and due to this, Mandrake-growers have found their plants nothing more than a bloody mess when they pull them out of the ground.
