Overview: Nok Tok sees Lau Lau whistle up to the sky and her narabug come down to land on her head. What a great trick! But when he tries, he discovers he can't whistle. All it seems he can blow are raspberries! Lau Lau tells him to blow gently and to practise. But when Yojojo realises that he is the only Pipling who can't whistle, he wants to get round the process of learning. When the children arrive, he tries to do the narabug call using a whistle stick instead, but it doesn't work like real whistling. Then he tries to use his Anything Machine to create a whistle sound, but that doesn't bring his narabug down either. The children try whistling too but one of them can't. So she encourages Nok Tok to practise with her. Now that he doesn't have to practise alone, Nok Tok applies himself and eventually they finally get the hang of it. Everyone whistles and all the narabugs flutter down and land on their heads.
