 The advertising featured King Vitaman and his knights, Sir Laffitup and Sir Cravenleigh, and their foes the Blue Baron and the Not-So-Bright Knight. The earlier commercials had King Vitaman tell his dimwitted knight to pour the milk over King Vitaman cereal, but instead the milk is poured over the king, prompting the king to say, angrily: "Not me, you dingaling, the cereal!" Subsequent non-animated advertisements ended with a jingle inviting children to "Have Breakfast with the King."
