Sound out, whistle

The Delphi kids are jealous of Peter's preference for Heidi. Onji comes down from the mountains to sell the wooden utensils he crafts and the cheese he makes to get groceries and all he needs in return. Convinced that the Delphi baker has tried to cheat him, Onji leaves angry and heads to a further village, where he gets a good deal. At his return, he finds Heidi home who is excited with all the things she's learnt during the day: now she can milk and whistle like a good goatherd. Onji observes her proudly and treats her with a yummy sweet he's bought for her.
