Big City Park - Captain Billy

May the friendly park keeper and her friends welcome enthusiastic young explorers to their park for a day of fun. Ruairi tells Billy about his time as a ship's captain, and Billy is keen to be the captain of a ship too and go on adventures like Ruairi. May, Dara, Billy and the children explore the park equipped with binoculars and magnifying glasses to see new things they have never seen before. They discover bird's nests, millipedes and other insects and interesting things. Billy concentrates on trying to spot any passing ships. The group decides it is a good idea to build their own ship in the park, and they use their imagination to help Billy achieve his ambition.
