Faulty Whistles is the twenty-sixth episode ever made in Season 6.
Peter Sam is delivering some goods, but on the way home, his whistle is knocked off by a branch. Duncan laughs and sets off with his goods. When he passes Terence in a field, he prepares to give him a surprise by tootin his whistle, but it simply flies off into the field. Luckily, one of Duncan's items to transport is an organ destined for Strawberry Grove School, and Headmaster Hastings plays the organ when Duncan should whistle. Duncan reaches home safely and is able to make good humour with the others.
