Charlie McGuffin has an incredible secret . . .
He can change into animals. All sorts of animals: a flea, a pigeon, even a rhino. Trouble is, he can’t decide when – it only happens when he gets worried. And right now, Charlie has quite a lot to worry about:
His brother (who is in hospital); His parents (who are panicking about it) and the school bully (who has Charlie in his sights) and even though every kid wants a superhero power, Charlie isn’t keen on changing into a chicken in the middle of the school play. So with the help of his three best friends, Charlie needs to find a way of dealing with his crazy new power – and fast!
