Sam pointed out to the ocean. We could see the front of a sailing ship appearing from the edge of the island. "Hey, it looks like a ship" said Fred. We clutched our trees and watched the front of the ship turn into what looked like a huge wooden ocean liner. Except this ocean liner had cannons. And it was flying a flag from its mast - a black flag with a white skull. "Oh no" said Fred. He went back up the tree. Fast.
