Yummy Mummy was a newcomer to the breakfast cereal triumvirate which comprised of Count Chocula, Boo Berry, and Frankenberry. It was obvious that the triumvirate couldn't hold its own so Yummy Mummy was recruited to help. The next year, all of them disappeared except Count Chocula, who is currently experiencing tough competition by Cocoa Puffs, Cocoa Pebbles, Reese's Cereal, Nesquik Cereal, and Milk Duds.
