Sonny The Cuckoo Bird is the mascot for Cocoa Puffs. In the Cocoa Puffs commercials, he goes 'cuckoo for Cocoa Puffs' when he sees a box or bowl of them.


In the commercials, Sonny attempts to concentrate on a normal task and ends up coming across some reference to Cocoa Puffs themselves (usually described by the adjectives "munchy, crunchy, chocolatey") and bursts with enthusiasm, exclaiming, "I'm cuckoo for Cocoa Puffs!".

He was designed by Gene Cleaves in 1962, but a new design was chosen in 2019. The old design can be seen on many retro shirts sold in stores such as PacSun and Delia's. He is currently voiced by Sam Riegel, who voiced Donnie in the 2003 to 2010 TMNT series and Emperor Awesome in Wander Over Yonder reboot.
