When Kwazii sees what seem to be three flying swords under the Pirate's Moon, he embarks on a quest to find the Sword of the Pirate King, which legend says is on a wreck guarded by magical flying swords. The "flying swords" turn out to have been swordfish, which love jumping out of the water, but the pirate sword proves to be real. Meanwhile the others are led on a wild goosechase into a kelp forest following the pirate wreck's drifting figurehead, a carving of a pirate cat, which they mistake for Kwazii.
