Behind the walls of one of the school lavatories, Mitchell, Becky and Templeton discover an ancient chamber; inside, there's a giant stone toilet guarded by the vigilant statue of a knight.

Mitchell discovers a way to alter time by playing with the hands on an old clock tower; he and his friends decide to play around with time.

Mitchell is blamed when things start disappearing around the school; he tries to clear his name with the help of Becky and Templeton.

Becky dreams of becoming the star of a big musical, but her singing is awful; when she falls asleep in class next to the radiator, she has an incredible dream in which she and her friends are pursued by a hideous musical beast called The Grackle.

Becky sets up a stall to sell healthy snacks, like vegetables; when it gets popular, Becky's stand poses a threat to the nasty, evil school chef.

When a creepy magical book transports Becky and Templeton back to Victorian times, Mitchell seeks to rescue them.
