"Making letters, Mommy." He says they are S, Q, O, and C. O was kind of a freebie since it came in that shape. He also made a rainbow, a square, planets ("mmmm, yummy planets) and then my favorite: the bottom picture is the phases of the moon. "Crescent, First Quarter, Gibbous, and Full Moon." I never have that much fun with MY Cheerios...and I didn't know about Gibbous until I was 34.
