Prizes in the couch

Look at that tail in action! Captain has been hiding that chew behind our couch pillows recently.... I keep coming home and finding the cushions pushed aside. He just looks at me, like, "What?" and then acts all surprised when I pull it out from behind the pillows. Then he runs it into his kennel or bed, re-hiding it (to re-hide in the couch again later). I'm starting to wonder if he'll ever actually eat that thing, or if we'll just find it, years later, stuck somewhere in the couch....
