Rachel and Kirsty to the rescue! The girls are spending a week of their summer vacation at the Wild Woods Nature Reserve. They're going to volunteer as junior rangers-- which means lots of quality time with all the animals who live there! But Jack Frost has taken the Baby Animal Rescue Fairies' magic key chains. Even worse, he's planning to use the fairies' stolen magic to kidnap baby animals for his icy zoo. Rachel and Kirsty have to keep Sheba the tiger cub safe from harm. If Jack Frost succeeds, Kitty may never get her back!
