Argelfeister: He is a reddish-brown fox with a tail hanging down at Pookey's wrist-level. The tail is tipped in white; the part that resides on the underside of Pookey's arm, his underbelly, is also white. Arg has typical fox-markings, along with several off-colour green splotches from where Pookey drooled in his sleep. The puppet's wings are the same colour as his fur, and covered in feathers. Skinny black legs hand limply on his "underbelly", the last two being before the tail. The rest of the sock trails down Pookey's arm. (I hope that description made sense.)
