Sonny, the cuckoo bird mascot of General Mills' Cocoa Puffs cereal, turns 55 this year. Following is Sonny's debut ad, even though at the time he didn't have a name. Actor-comedian Chuck McCann, known at the time as a kids' show host in New York, is the voice of Sonny here.
For the last few years, Larry Kenney (ex-Thundercats) has been the voice of Sonny, while McCann eventually returned to voice Gramps when the latter character resurfaced in 2010. And, yes, Sonny still goes cuckoo for Cocoa Puffs, at 55.
