"Dr. Go" is an episode of Special Agent Oso.
Wolfie trains Oso to water ski up a ramp and jump into the lake without falling. A special alert is called after Oso jumps off the wrong end of the ramp and takes a face first plunge. A girl named Emily wants to her brother's remote-control car while he and his friends change the tires on theirs, but she doesn't know how it's done. It will be up to Oso to teach her how to race the car before the boys get back.
