Many cereal mascots are featured on all in the series(e.g. Snap! Crackle! Pop! appears on every variety of Rice Krispies, not just regular Rice Krispies, and Cap'n Crunch appears on every variety of his cereal, not just the plain version). But why does Buzz, the Honey Nut Cheerios bee only appear on Honey Nut Cheerios, not on every variety of Cheerios?
