Farmer Lucy brings her petting farm to Biggleton but when she leaves the gate open, all the animals go missing. Luckily, Police Officer Liam is on hand to help. They set off to track down the animals and before long they find the missing pig and sheep. When they find the missing cow, however, they can’t get her to come back to the farm. Despite some help from their Biggleton friends, they can’t get the cow to budge. She doesn’t like their dancing and she doesn’t seem to be hungry. Finally, Dolly the Popstar discovers how to get the cow to move.
