The Green Team are going tracking. Every creature makes a different print, but can they recognise them? Green Balloon Club members Joanne, Jack, Jonathan and Niamh are on the East Anglian coast looking for a beautiful bird called an Oyster Catcher. The Ground Crew set off on a tracking mission too and find something quite a bit larger. Cat finds out about Hares, whilst Lily-Rose and Ant make a peacock using their own prints.
