Fly on the Wall / My Sweet Ride

S4, E1: Buford removes a part from a giant tyre swing ride the boys are building. It shoots off a ray that turns Candace into a fly. She has to live like one until the boys rescue her. Candace has always dreamed of having her own car, and when it's time for Danville's Doo Wop Hop and car show she finally gets her wish, but it's not quite what she imagined.
