Story : In a desert-like landscape Plif and Plops find a golden coin and immediately mark a territory to dig for gold. Only a tiny piece of desert is left for Plummy. While Plif and Plops can find only scrap metal, Plummy is digging up one golden coin after another and some pieces of jewellery. Plif and Plops get very jealous and steal Plummy´s treasures. Plummy seeks revenge in a very crafty way: he dives into an Aladdin's lamp and returns as some sort of Djinne. The „Djinne" is in a rage and accepts nothing less than the return of the stolen treasures. Afterwards Plummy shows them what coins are really good for in a desert : he morphs himself into a big vending machine, inserts one of the coins and buys each plonster a tasty lemonade.
