Where's my pencil?

Ok, so I am house sitting again. With the dog that likes to bring in tons of things. Well I was working on homework and left my books and pencil on the coffee table. I leave it there for a bit and go work on other things. I go back in there a few minutes ago. I could have sworn I left my pencil on top of my books but there was nothing there. I recalled how an hour or so ago I was picking up broken pieces of a toy and there were little clear pieces that were there and thought it was odd because I didn't think it fit with the toy.

Anyway I go to the spot not recalling any other part of a pencil but I look where I cleaned up the toy and this is what I found....
Pencil's have springs right? I thought they did. This dog, I swear cannot be trusted! If this dog ate my pencil, there is no telling what all he has eaten.
I may have to start an Ode to Pencil blog post. :(
