What happens when you feel stressed? Maybe you start sweating, or your heart beats faster. When Charlie McGuffin gets stressed, something a little bit different happens: he turns into an animal! Unfortunately, things are getting quite stressful for Charlie:- His dad's business is in real trouble - He might have to move in with his Aunt Brenda and her seventeen cats (and wooden leg) - And it's getting harder and harder to control his powers. Luckily, Charlie's best friends Flora, Wogan and Mohsen are on hand to help. If they can break into the fortress-like offices of Van Der Gruyne Industries and recover the McGuffins' stolen gold, maybe Charlie won't have to move away after all.
