"The Powerpuff Girls" is Cartoon Network's highest-rated show among kids 2-11. It's a mega-hit! And so are Scholastic's books -- last year's Valentine Book hit #9 on the NY Times Kids' Bestsellers.The Powerpuff Girls' rival, Princess Morbucks, is up to no good again. The bratty kindergartner has a new toy that can shrink people down to doll-size! Now she's shrinking down anyone who tries to stop her. It's up to Blossom, Bubbles, and Buttercup to stop her -- but can they do it when they're only two inches tall??
