The Mrs. Piggle-Wiggle series stars a small lady who lives in an "upside-down" house in a lively neighborhood inhabited mainly by children who have bad habits. Mrs. Piggle-Wiggle has a chest full of magical cures left to her by her deceased husband, Mr. Piggle-Wiggle, who was a pirate. In the first two books of the series, Mrs. Piggle-Wiggle (1947) and Mrs. Piggle-Wiggle's Magic (1949), Mrs. Piggle-Wiggle provided parents with cures for their children's bad habits. Cures range from the mundane, (the Won't-Pick-Up-Toys Cure involves allowing a small boy to continue leaving his toys scattered about his room until the room becomes so messy he's unable to escape from his room) to the fantastic (the Interrupting Cure is a special powder that is blown on the interrupter, with the effect that it causes the person to become temporarily mute every time he/she tries to interrupt someone). In the series' third book, Mrs. Piggle-Wiggle's Farm (1954), Mrs. Piggle-Wiggle sells her house in town and purchases a farm, where with the assistance of a large assortment of animals she continues to help children overcome their bad habits. In this collection, Mrs. Piggle-Wiggle uses no magic for her cures; the farm itself does the most good. In the fourth book, Hello, Mrs. Piggle-Wiggle (1957) she has apparently returned to her original neighborhood and to her magical cures. No mention of the farm is made for the rest of the series.
