When Granny hears the Drysdales are at a horse show, she declares she wants good trotter so she can ride it to the market. When Mr. Drysdale buys a racer along with a buggy, Granny decides she wants to be the driver at the track.

Granny encounters an ostrich at the Drysdales and believe it's a giant chicken. She decides it got into her "medicinal tonic" and that's why it's so big. She tries to apply the idea to her vegetables.
