The Milkybar Kid has been used in television advertising promoting Nestlé Milkybar in the countries where it is sold. The Milkybar Kid is a blond, spectacle-wearing young child, usually dressed as a cowboy, whose catchphrase is “The Milkybars are on me!”. Until 8 year old Hinetaapora Short of Rotorua was selected in 2010 they had always been boys. The advertisements usually take place in a Wild Westsetting. Both live-action and animated ads have been produced.
