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 occassionally 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.

When Ron Weasley was to write an essay on resisting Dementors in his sixth year for Professor Snape for the Defence Against the Dark Arts, due to the Spell-Checking Quill's effects eroding from time, the term "Dementors" on the essay changed to "Dugbogs".
