It's a Mystery

Matthew is always "seeing" shapes and objects in his food. He will take a bite of a Saltine cracker and then "see" the letter D, a goat, you name it.
Today at lunch I was putting grapes on his plate and he says, "Mommy, it's a mystery!" A mystery? Upon further research, I found out he meant a question mark.

This picture isn't how they really looked when they dropped on his plate. I rearranged them. =)
