The Fantastic Flying Journey
 One day, a hot air balloon attached to a huge straw house, lands in the garden of the Dollybutts. The fat old man who owns it is Great-Uncle Lancelot. He tells Mrs Dollybutt and her three children that he is going to find his brother, Perceval, who is lost in the jungles of Africa, looking for gorillas. Perceval, a scientist, invented a magic dust which enables people to communicate with animals. Lancelot takes the three children, Emma, Ivan and Conrad with him in the hot air balloon, which he has called Belladonna, to track Uncle Perceval. On their way, they meet several animals which they can talk to (because of the dust), such as a swallow, a camel and a fennec fox, who tell them many interesting facts about their lives. In the jungle, the gorillas tell them that Perceval left for South Africa, to meet some elephants. Lancelot and the three children follow Perceval to South Africa, and then to Australia,the North Pole, Canada, North America, Brazil and Patagonia. On their way, they meet a crocodile, a rhinoceros, some koalas, a platypus, a blue whale, some killer whales, polar bears, musk oxen, beavers, buffalos, monarch butterflies, a boa constrictor, some howler monkeys, penguins and elephant seals. Everywhere, they learn something about the animals, their habitat, behaviour and dangers threatening them. In the end, the elephant seal tells them that Uncle Perceval has returned to Britain. So they follow him there, and find Perceval in the Dollybutts' house. The chase lasted a whole year, but the children all agree it was not a waste of time after all.
