Zerby Derby is a British-Canadian live-action television preschool series that was created by Phil McCordic. Produced by make believe ideas in association with CBBC, Kix, and Cbeebies, the series premiered in UK on CBBC and Kix on August 29, 2013. It airs on Sprout (TV network) in the US. Its Spanish version (shown on BBC Espanlo) is called Zoubi Doubi.
The series follows the adventures of anthropomorphic motor vehicles Zack, Lily, Rex and Axle as they embark on daily adventures of crossing streams, building dams and exploring meadows, approaching every potential problem with cheerful enthusiasm. No obstacle is too large for the Zerbies, thanks to their mantra "try, try again!". The vehicles are remote-controlled and also employ moving eyes for added expression.
