Something has appeared in the boys’ lockers. Don’t wake up the most da-dangerous of the kni-knights of old, the terrible Sir Toi! The twins and their friends will pay dearly for this mistake: exam time will stretch out like already-been-chewed gum, Gracie won’t let them get out of the tub… all of the worst moments will go on for an eternity, and the best ones are over in the blink of an eye. The twins and their pals have to do something. Will Zip and Zap be able to put Sir Toi back to sleep, or will they be doomed to live forever trapped between Prof. Minervo’s endless exams and Gracie’s soapy sponges?
