What in the Name of Christmas is This Thing?

As we wind down opening the cheapest advent calendar known to mankind, this was the piece of chocolate for Monday the 21st. What is it?? I don't even have a guess!

My favorite thing to do with this advent calendar is find something dirty about the chocolates - but I can't even do that with this piece!

Okay...what's your best guess. If I had to guess, I would say holly? Or roadkill.
