Just when you thought the fairies couldn't get any cuter. . . here come the baby animals! 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 must help Rosie get her magic key chain back. If they don't, Billy the honey bear cub might end up in Jack Frost's zoo!
