Usually once a cereal mascot gets popular, they stick around. Oh sure the designed may change or be refined, but it's the same character. Some cereals have trouble finding that perfect gimmick however. And even when they do the character inexplicably disappeared after a while. Usually the mascot vanishes because the product did (Poor Fruity Yummy Mummy) but not always. The creators just decided they had enough of one mascot and it was time for something new! This makes sense when the product is brand new and searching for an identity. Frosted Flakes had a kangaroo before they realized Tony was better. Cocoa Puffs had an uncle for Sonny who vanish (but did make a comeback) and even Lucky Charms dropped Lucky for a lame wizard. It didn't take.
Here are five cereals which had more trouble with mascots, switching them out for no really good reason,
Cookie Crisp
Ok I am going to date myself here and freely admit it. I remember seeing the old commercials with the wizard Jarvis. He was a wizard in the 70's. Jarvis later introduced cookie crook and the officer chasing him whose name eludes me. There were several commercials of these two before cookie crook got a dog sidekick. The dog always giving away the crime by crying coookiee crisp. These three did a bunch of ads before the cop and robber vanished and it just became about the crazy dog. But he outlived his usefulness eventually and today we have the silver fox in a jacket guy, if he has a name, I don't feel like looking it up. And yes I at Cookie Crisp and loved them, it's chocolate chip cookies for breakfast what's not to love???
