And he has a whole on his head that enlarges for no reason at all whatsoever. I would have gotten a picture, especially since BW is enthralled with it, but I was pretty convinced that hole was going to morph into a giant tooth-filled, slime-spitting mouth with an extra long neck that was going to reach out and eat me.
So I left BW alone with it. If I don't see him in a few hours, I'll assume he's dead. At which point maybe I'll send a dog or two out to see if they can kill him.
