Pippi Longstocking is the fictional main character in an eponymous series of children's books by Swedish author Astrid Lindgren. Pippi was named by Lindgren's daughter Karin, who asked her mother for a get-well story when she was off school. Pippi is red-haired, freckled, unconventional and superhumanly strong – able to lift her horse one-handed. She is playful and unpredictable. She often makes fun of unreasonable adults, especially if they are pompous and condescending. Her anger comes out in extreme cases, such as when a man ill-treats his horse. Pippi, like Peter Pan, does not want to grow up.
