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!
