May the friendly park keeper and her friends welcome enthusiastic young explorers to their park for a day of fun. May, Billy, Dara and the children go exploring in the park but Billy is worried about getting lost. Ruairi tells Billy that he will try to find his old map of Big City Park to help him find his way around. They all decide to make signs out of things they find in the park. Dara consults her friends in the city to see how they find their way around and they show her how they get to their favourite park. Ruairi can't find his map so he draws a new one to help them all to not get lost. They all tuck into the treats that Ruairi has made for them and they place one of the beautiful forest mobiles they have made into Ruairi's treasure chest.
