The fairy king and queen have just put together a new team of seven fairies for a very special mission. Together, they're going to work their magic to clean up the environment. But they can't do it alone: Rachel and Kirsty are ready to help. In this installment, the girls are volunteering for a gardening project: they're going to turn an unused lot into a beautiful garden. But first they need to find Edie's missing wand--before it's too late.
