Izzy and her friends are really surprised when Miss Jones starts being nice to them. After all, this is the teacher who secretly smiled when Maisie Miller fell off her chair that time. And then a teddy bear appears on her desk, with “You're Great” written on its tummy. Miss Jones isn't a teddy bear kind of person. She's more of a hates-puppies-and-thinks-kittens-are-ugly kind of person. And that's when they know – Miss Jones has been taken over by aliens. And now she's trying to turn them all into aliens, too. RUN!!!
