It has to be said that the dragon knows no greater fun than to fry the king’s moustache for breakfast… As for Princess Melody, well, she happens to think that the dragon is quite adorable! And then there’s Riri, the court jester, secretly in love with Melody, and ready to do anything for her. Helped by his faithful friends Juju and Merlin the Magician, he quietly starts making plans to foil the attempts of all knights who dare answer the king’s call to arms. The dragon, meanwhile, looks set to have a LOT of fun!
