Origin: Scottish mythology
Habitat: Scottish highlands
Cu Sith is a legendary canine about the size of a calf, with dark green fur and a braided or coiled tail. It leave paw prints on the sand that disappear halfway across the beach.
It hunts silently in the fog, but has a bark loud enough to be heard by sailors at sea. If it barks three times, nursing mothers should lock their doors, as Cu Siths have been known to abduct mothers to supply milk for their offspring.
