During the graduation ceremony for the new Knights of Knighton, Jestro the jester is ridiculed for his terrible, uh, jestring. Distraught, he's seduced by the powerful and evil Book of Monsters until Merlok the Magician tries to stop Jestro by using his most powerful magic spell.
After a magical explosion, Jestro discovers that he still has the Book of Monsters and together they decide to attack and destroy the Kingdom. Their monsters seem like too much for the new Knights of Knighton until an old friend emerges in a new form.
When Jestro and the Book of Monsters start using their monsters to ravage the countryside, the Knights get an awesome new HQ to fight him, the mighty, powerful Rolling Castle known as the Fortrex.
