Oliver's mum has caught Green Flu so Oliver is in charge of all the housework. There's a lot to do - recharging the wands, washing the cloaks, not to mention looking after the Witch Baby and her pet spider! Everything is okay until Oliver tries a Grow-bigger spell on the cauldron. Then he finds himself in very BIG trouble indeed.
