Mr and Mrs Bold are just like you and me: they live in a nice house, they have jobs and they love to have a giggle. One slight difference: they're hyenas. That’s right - covered in fur, tails tucked into their trousers, and they really like to laugh.

So far, the Bolds have managed to keep things under wraps.. But the nosy man next door smells a rat, could this be the end of Teddington's best-kept secret?
