The Coop Troop answer a call from Cornelius. He has a poppy seed stuck in his teeth and it's quite uncomfortable. They zip over, take it out and go back to the farm, only to realise later that Jo is missing. Clive, Maggie and Billy can only assume that Cornelius has swallowed Jo. Not wanting to worry Flo, Billy stays behind to distract her while the other two rush to town to get Jo out of Cornelius.
