We've seen this fella on blip before. He's one of Joey's soft toys.
Joey knows that he isn't allowed on the furniture, but he does sometimes sit on the sofa by the window when there's no one else in the room. I often hear him jumping off the sofa as I'm coming downstairs. Today he left some evidence behind (apart from the dog hairs, that is). He clearly wanted some company on the sofa today, so he brought one of his boys up there too. Thing is, he forgot to remove it when I came downstairs this afternoon.
