General Mills’ Monsters cereals—Count Chocula, Boo Berry, and Franken Berry—are being reimagined as fuzzy puppet characters through a new collaboration with the Jim Henson Company, which is celebrating its 70th anniversary. Since their debut in 1971, Monsters cereals have been a seasonal staple, General Mills says.

Starting in August, limited-edition boxes will hit shelves featuring puppet-themed versions of the Monsters. Consumers can flip each box for a look at how the team from Jim Henson’s Creature Shop used their puppet-building expertise and artistry to reimagine the characters as part of the family of monsters from throughout The Jim Henson Company’s 70-year history.

In addition, beginning Tuesday, October 7, a fuzzy Franken Berry box—designed to mimic the fleece-like texture of the newly created puppets—will be available exclusively on Walmart.com for $7.70.

“This is more than a cereal box, it’s a piece of art,” says Mindy Murray, brand experience director for morning foods, General Mills. “We know that fans have an incredible love for Monsters and anticipate their return every year. That’s why we knew the partnership with The Jim Henson Company was the perfect way to deliver surprise and delight—and the first-of-its-kind fuzzy Franken Berry box.”  

“For 70 years, The Jim Henson Company has brought some of the world’s most memorable and  adored characters to life and our incredible team at Jim Henson’s Creature Shop especially enjoyed realizing these beloved Monsters as puppets for the first time ever,” says Nicole Goldman, EVP of branding for The Jim Henson Company. “This irreverent and funny take on these well-known characters will make this Halloween especially memorable for the amazing and loyal fans of both Monsters Cereals and The Jim Henson Company.”
