Herky and his friends are eagerly anticipating the Rivertown Fair. When Herky comes down with Upsy-Downosis, a cold that planes catch, he ignores his illness so he can get his work done before the fair. But when Herky messes up an important delivery for Brenda Blue, he learns an important lesson about telling an adult when he's not feeling well.
