Because of the high gasoline prices, the Mayor travels to the oil-producing country Labu-Dabu. He wants to do a deal with the Sultan over a direct pipeline to Newtown. Bibi and Carla Caramba go along with him. When Bibi and the Mayor return from the basar, Carla has been taken into the Sultan's harem. He will only let her go if they manage to solve a special puzzle. Luckily Bibi has a tame genie who solves the puzzle and finds treasure. In the end, Bibi turns an oil well into a water source and the pipeline doesn't get built after all.
