A full-length animated film.…They met on one of those unfortunate days when being a PeeWee was no fun, though usually to be a PeeWee was wonderful. He stood sadly by the window looking onto the street. Suddenly he heard some light buzzing and a cute little chubby man with a small propeller on his back flew by. It was Karlsson, the world’s best flier and champion in high-speed eating of sweets. And whenever Karlsson flew in, some extraordinary adventures began, because he was the world’s best inventor of all kinds of mischief…Based on the book by Swedish author Astrid Lindgren, the two-time winner of the Hans Christian Andersen Medal, the highest international prize for best children’s books.
