The Prickle SistersLittle girls grow up. This doesnt just apply to the young and perhaps already slightly older fans, but also to the little Prickles themselves. Or is it best to say the Prickle sisters from now on (for our own safety)? After their adventure in the Haunted Mill (included in full in this book), the infamous family moves to the city, and the sisters attend secondary school. Cool, because then they can torment not just one, but several teachers there.
