In an old Spanish fort on Cactus Island in the Caribbean Sea Cut-Throat Jake was having a party.

It was evening and he and his ugly crew had brought from their ship a great hoard of treasure to bury in the ruins next day.

They ate and drank from the golden plates and goblets and sang and danced and told terrible jokes to each other. They thought of course that nobody knew they were there.

They would not have been so happy had they known that close by, with his ship the Black Pig hidden behind high rocks, was Captain Pugwash! 

And they would have been even less happy to see, moving in the shallow water near the ship, clear against the setting sun, a most odd looking sea monster.

Close up it looked odder still!
