Dinkin Dings and the Curse of the Clawfingers (Book 3)

Dinkin has made a big mistake - he's created an invention of such mind-boggling anti-everythingness that it's far too terrifying to use and must be destroyed at once. But before he can get rid of it, the Anti-Everything Machine is stolen. Can Dinkin and the Frightening Things find the thief and save themselves from a fate worse than terror?
