Pirate Edwin Peas needs his old friend Aunt Zelda's help. It seems that King Feargus II of Ootnanni has taken some of his ship's crew captive and won't return them until Eddie coughs up the loot he stole. Too bad he can't remember where he hid it. A greedy Salem sets out with Sabrina on a high seas adventure to recover the sunken relics -- and they end up in a titanic mess.
