Crazy Cow is always doing crazy things. She does headstands on the school flagpole and bungee jumps from the roof, but she never does her homework. Everyone is amazed by Crazy Cow's antics, but her parents just don't know what to do with her. Since her babyhood, Crazy Cow has been swinging on lampshades, turning cartwheels across the lawn and doing acrobatics whenever and wherever the mood takes her! In Gym lessons she's the star, but in the rest of her subjects, her teachers despair.
When Crazy Cow leaves home to seek her fortune, her parents are very worried about where she'll end up. The one day, Mr and Mrs Cow go to the circus, where an encounter with The Great Krazo, shows them that craziness can be quite fantastic . . .
