What is it??

If you can identify (within reason) what today's ornament is from our advent calendar, you win a chocolate bar!* And yes, I'm asking because I have no clue what this is. Jake and I had a really hard time getting this particular ornament out of the box, and when we finally got it out, I couldn't identify it. Jake laughed.

So leave me a comment if you think you know what #10 is.

*USA residents only... if you are international, you'll get something next time I see you :)
