Cereal Wiki

Sonny the Cuckoo Bird is the cartoon mascot for Cocoa Puffs, a General Mills-produced cereal. He often appears in its television commercials.


In most commercials, there is a running gag where Sonny attempts to stay away from Cocoa Puffs, by doing a different activity, but ends up coming across some reference to the cereal in the act (usually described by the adjectives "munchy," "crunchy," and "chocolatey"), causing him to burst, exclaiming "I'm cuckoo for Cocoa Puffs, cuckoo for Cocoa Puffs!"

He was designed by Gene Cleaves in 1962, but a new design was chosen in 2004. The old design can be seen on many retro shirts sold in stores such as PacSun and Delia's. Sonny was originally voiced by Chuck McCann. From 2005 to 2008, Sonny was voiced by Tex Brashear. He is currently voiced by Larry Kenney, who voiced Lion-O in the original 1985 Thundercats series and Claudus in the 2011 reboot. Chris Phillips, Dave Shea and Roger Craig Smith have also voiced Sonny The Cuckoo Bird.

Sonny's name comes from the original format for the commercials, in which he was paired with his Grandfather. Rather than proper names, they always referred to each other as "Gramps" and "Sonny." When the Grandfather was dropped from the ads, "Sonny" remained as the character's name. In those original spots, both Sonny and Gramps were voiced by Chuck McCann. However, in 2011, Grandfather (again voiced by Chuck McCann) returned in an ad for Cocoa Puffs.
