Cocoa Puffs is a brand of chocolate-flavored puffed grain breakfast cereal, manufactured by General Mills. Introduced in 1958, the cereal consists of small orbs of corn, oats and rice flavored with cocoa. Essentially, Cocoa Puffs are Kix cereal with chocolate flavoring. Kix cereal is produced in the same factories as Cocoa Puffs, but differs in density and circumference. The mascot of Cocoa Puffs is Sonny the Cuckoo Bird, whose catchphrase is "I'm cuckoo for Cocoa Puffs!" was introduced in 1962. On several occasions, Cocoa Puffs boxes stated that they are made with real Hershey's chocolate. Cocoa Puffs are sold in Canada, Latin America, Mexico and Europe under the Nesquik brand, thanks to a partnership between Nestlé and General Mills; Nestlé and Hershey are competitors in the chocolate business. A cereal bar of Cocoa Puffs has been made. A layer of dried, sweetened condensed milk is added to the bottom, and marketed as a substitute for a bowl of milk and cereal. The newest addition was introduced in the summer of 2008, Cocoa Puffs Combos, which consists of the recognizable chocolate puffs with vanilla puffs. Unlike original Cocoa Puffs, the Combos cereal does not contain cocoa.
