The stories aren't coy about the fact that they set out to show how kids ought to behave, but they're so much fun that I don't think anyone minds that they teach a lesson. After all, who minds when Mrs. Piggle Wiggle is the teacher? These stories, unlike those in the other 3 books, are set on a farm, and teach kids about responsibilty, self-reliance, and trust. Read them if you have kids, read them if you don't have kids. Just read them!
Ms. Piggle-Wiggle's left her upside-down town house and has moved to a farm in the country. With the help of her cows and pigs and horses, she's still curing girls and boys of their bad habits. So whatever the problem-from pet forgetter-itis to fraidycat-ness-the parents all exclaim, "Better call Mrs. Piggle-Wiggle!"
