When King Eggnog rashly offers the hand of his daughter Princess Miranda in marriage, Sir Bigwart sets out on a daring quest with his faithful squire Toby in tow. The quest is to bring back a tooth of the Ogre of Ghastly Fell, a fearsome, flesh-eating giant whose breath is so bad it can knock you at a hundred paces and whose two heads are constantly squabbling with each other.
Sir Bigwart's real talent is for empty boasting so he's going to need a lot of help from his resourceful squire on the way — which is a little awkward since Toby is secretly in love with Princess Miranda himself. To make matters more complicated, Miranda is bored of embroidering her dad's coat of arms on cushions — she's coming along for the ride and anyone who tries giving her orders had better watch out.
