S1·E18 Zephie's Zoomaround
Aired October 16, 2008
Synopsis
On her way to see a lamb at the farm, Zephie gets lost! She shouts for help and rings her little bell, but no one hears her. Morgan fits her with a siren so that she can call for help if it ever happens again. Zephie falls in love with her new accessory and can't resist playing with it and setting the siren off - much to the annoyance of the other chuggers.
