Mr and Mrs Bold are just like you and me: they live in a nice house (in Teddington), they have jobs (like writing Christmas cracker jokes) and they love to have a bit of a giggle. One slight difference: they're hyenas. Yes, that's right - they're covered in fur, have tails tucked into their trousers, and they really, really like to laugh. So far, they've managed to keep things under wraps, even when their children were born. But the nosey man next door smells a rat (or a hyena), and a trip to the local wildlife park, and the brilliantly wacky heist that results, could be the end of Teddington's best-kept secret. Whatever will the neighbours think?
