Granny Grabbers' Whizz Bang World

Delilah Smart is just an ordinary child who wants to have a normal childhood, but her parents have other plans. They are determined that she wins the Worldwide Junior Extreme General Knowledge Competition and in order to achieve this Delilah must cram all day and only play with educational toys like the Sir Isaac Newton Brain Building Bear. And because Mr and Mrs Smart are Very Busy People they buy a 'childcare robot' to do the boring stuff like looking after her.
