Following the complex clues which promise to lead to Martin's Sword, Matthias climbs high into the abbey roof - and the kingdom of the crazy King Bull Sparra. A feisty sparrow returns a kindness and addresses him as King Sparra flies to attack Asmodeus - who has Martin's Sword! The king returns in time to fight who narrowly escapes death. But at least Matthias knows where his sword quest must end in a battle against the vile snake!
