A pirate with a map meets up with another pirate with a boat and crew and they sail to the island or Ooroo where there is supposed to be treasure buried. The map they have doesn't have the location, and they ransack the island looking for it.
The captain of the boat hates the letter O and gradually tries to rid the island of it, either taking the Os out of words, or getting rid of the things themselves. The islanders plot to defeat the pirates, finding the important O words that will enable them to have the power.
Interesting but not a favourite.
