Zed and Pink are a normal brother and sister except for one thing... their mum is a Very Naughty Mother.

One morning the Very Naughty Mother with her children Zed and Pink are sitting in a tree having a normal family breakfast of fairy floss and honeycomb wrapped in cheese and ham and chocolate, when the phone rings. A rumbling voice like thunder instructs the Very Naughty Mother to fly to Planet Plopabitofpoop – immediately! Not tonight or tomorrow morning or in ten years’ time, but right now! Zed and Pink demand to know why. She doesn’t want to tell them, but they won’t let her go until she does, so she whispers something about having to stop the birdies.Does she mean baddies? And does it have something to do with the top-secret new job she claims to have? Could the Very Naughty Mother possibly be – a spy?
