Greek yogurt—thick, sharp-flavored and usually unsweetened—is not generally thought of as a children’s product. But AgroFarma, New Berlin, N.Y., has brought out a kids’ version of its Chobani Greek yogurt that uses packaging as part of its appeal. Chobani Champions yogurt, in Chocolate, HoneyNana, StrawNana and VerryBerry, features colorful cartoon-style graphics on its serving cups, downsized to 4 ounces to accommodate smaller appetites. The cups come four to a tray, which bears printed games for the young consumers.
