Boyface and the Uncertain Ponies

Uncertain Ponies are making the inhabitants of Stoddenage-On-Sea very unhappy. Ponies have turned (back) into zebras, and suspicion is falling on the Antelope family's stripemongering shop as the source of the problem. Could something have gone wrong with the Quantum Chromatic Disruption Machine, and can Boyface Antelope and his friend Clootie Whanger fix it before all of Stoddenage-On-Sea's ponies are affected?
