Stop! Robot!

Wally is an eleven-year-old whizz-kid who builds robots that perform everyday tasks like weeding and ironing. Word of his talent spreads, and when the sinister Dr Criplash offers him a small fortune to build a special robot, it looks like an opportunity too good to refuse - his family needs the money.

But Wally is horrified when he discovers what the robot will be used for. He and his friends are soon plunged into a world where nothing is what it seems and nothing works the way it's meant to. And if he doesn't do what the evil doctor wants, his nearest and dearest will pay the price.

Can Wally outwit Dr Criplash, save his family and find a way to stop the robot from doing what it was designed to do?
