A gargoyle head who guards the Night Master's Lair and seems to have the ability to tell if someone is evil enough to enter. He apparently knows Kraggler. In "Gone-A-Fowl" it is revealed that he knows about "The Dark Tomorrow", which he described to Coop as "dumb Woo Foo name for something, and that it'll be awesome." He is no longer active after the Night Master's castle caved in.
