Molly examines her shelf of special things at the back of Mack's stall. She chooses the litter badge and remembers the day she got it... \n\nDaisy has a day off and Mack wants to spend the afternoon alone with her. Daisy wants to pick up litter on the beach, and Molly volunteers to join them and invites all her friends to come along too. Mack isn't thrilled about this. As the kids gather the equipment together, Moira's precious whistle gets knocked into Molly's bucket and ends up mixed up with all the litter that is going to be recycled. But Moira is too embarrassed to admit to Mrs Juniper that she has lost her whistle, so how will she get it back?
