Monster Cereals 2026

For the past 55 years, Monster Cereals have been a staple of horror-lovers’ breakfasts each Halloween season. Everyone knows these iconic cereals with the horror-shaped marshmallows: the chocolatey “Count Chocula”, the strawberry “Frankenberry”, and the blueberry “Boo Berry”, and some other fun friends over the years. 

In 2025 Monster Cereals partnered with The Jim Henson Company to reimagine these beloved characters as puppets. 2026 brings an encore partnership. “Fans loved Count Chocula, Boo Berry and Franken Berry reimagined through The Jim Henson Company’s creativity last year, so we were excited to team up again to create fresh new packaging designs that celebrate the characters and bring even more Halloween fun to store shelves,” said Megan Brooks, Business Unit Director for Family Favorites Cereal at General Mills.

“Last year, our team from Jim Henson’s Creature Shop had so much fun bringing these beloved Monsters to life as puppets, and we know our fans will enjoy seeing them again this season for more memorable magic,” said Nicole Goldman, Executive Vice President of Branding for The Jim Henson Company. “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.”
