Monsters Cereals and The Jim Henson Company Reunite to Celebrate 55 Years of Halloween MemoriesGeneral Mills is pouring a bowl of bewitching fun with the return of the limited-edition Monsters Cereals. This year marks the 55th anniversary of Count Chocula, Boo Berry, and Franken Berry, and to celebrate, the iconic cereals are returning with newly designed packaging and the reimagined puppets created by The Jim Henson Company, first introduced last year. Over the years, the Monsters have become a beloved tradition — from larger-than-life mascots to sought-after collectibles — always signaling the start of the haunting Halloween season. “And new this Halloween, we’re giving cereal and Jim Henson Company fans alike the chance to put their creativity to the test by transforming each cereal box into its own Monster puppet.” The limited-edition collection of Monsters cereals will be available in retailers nationwide later this month.
