Yakkity finds out that his grandfather Yardly Yak was a champion grass-eater who was cheated out of a first place trophy by a rival known as The Cowinator. Granny persuades Yakkity to challenge Cowinator to a grass-eating contest and restore the family name. The Cowinator accepts the challenge but because he's too old to compete he forces his grandson Cowinator III to compete for him.

Yakkity decides to build a float of his own for the annual parade when the town fails to recognize his comedic hero.
