Supermarket...Goodies?

The other day we went to the grocer store to stock up on food. Like always we would split up. I would go for the coffee, creamer, eggs and more. While the others would go for the poultry, beef, pork, fish and more.

Well, as I was strolling through the aisle I came upon the Chocolate section. I figured, since I was there and I have been working so hard, that I would get myself a snack: Chocolate. So I looked through the selection of chocolate that they had and came upon this...

This made me change my mind about getting a snack.

Now as you can see, the chocolate is wrapped in a plastic wrapper (squint your eyes to see the plastic). If you would focus your attention to the upper middle part of the chocolate, you would see teeth marks (look at the picture below to get a better look).

Now knowing that the store wouldn't put food products that have teeth marks on them on the shelf, I can safely assume that this was done after they had put the chocolate on the shelf. The question is, who or what made the teeth marks.

Based on the shape of the teeth marks and the indentation of the teeth, I can definitely say that a child made this. Perhaps a baby. Maybe, he/she had managed to get their hands on it and put it in their mouth. I mean, come on. Its the only logical explanation. Being embarrassed, the parents immediately put the chocolate back and walked off.  

Right?
