Arnaud, previously met in The Ogre’s belly finds himself too old for outdoor play. He appears to have mutated into the king of grouches, and so will be kidnapped onto Captain Crankypants’ celestial ship, which strangely enough, runs on grouses and grumbles. Fortunately, Loïc, Arnaud’s little brother, is not too old to trust Dylan of the Mountains, a gentle dragon who has come to Arnaud’s rescue. Armed mostly with good faith, they pair off to save Arnaud. Captain Crankypants better be wary!

Crankiness might be the order of the day for Arnaud but will he really enjoy being forcibly enlisted on Captain Crankypants celestial ship?
