i know this topic may be old but i know something that neithers prirates or ninjas want you to know of...
THE DREADED PIRATE NINJA (or ninja pirate)
Imagine, it's dark out, and you're on a ship at sea when all of the sudden, men come leaping onto your ship from 200 feet away. You try to warn your crew members but it's too late... Their throats have already been slit. They are all dead...
Then they take your treasure, jump back to their ship, and party like no other!
