One of the last commercial series Hanna-Barbera produced for Kellogg's enabled Corn Flakes mascot Cornelius the rooster to come to life. Actor Andy Devine (ex-Wild Bill Hickok) is the voice of Cornelius. While the child is real, his voice was dubbed over by Dick Beals (Frankenstein, Jr.). In the second spot, Cornelius meets Christopher Columbus (Paul Frees).
Too bad Cornelius was ultimately forced to retire from television.
