Kids cereal marketing is fascinating, from the toys to the way the mascot's eyes tend to look down [1]. I didn't get to make a lot of decisions as a kid, but cereal was one of them.
I was also exposed to another strange aspect of cereal marketing: the sugar content. My father instituted a rule that we could have any cereal with <= 10 grams of sugar per serving, and so my sister and I became acutely aware of said levels. Captain Crunch was out of the question, but Cinnamon Toast Crunch would dip above and below the line, with a period of several months. Nearly all cereals I watched displayed this behavior.
