Mary is a young girl who loves macaroni and cheese. She can tell what shapes the noodles are, no matter what, even with her eyes closed. Mary doesn't really talk with many kids outside of school, but Etzor is the first one she really did speak with at all, when he gave her some mac and cheese. She sits next to him in Science class, and they started talking when he let her copy his homework, because she forgot to do it.
