Once there was a pirate who buried his treasure at the bottom of the sea but he forgot were it was. It had been five years and he had never found it since and no one else had found it either. Because the other people don't know he hid it and that he hadn't found it.
But one day some people went in a submarine and saw this pirate and helped him find his treasure. No one found it either and it had been five more years now. Then some more people came down but they didn't help the pirate and people. Because they wanted the treasure for themselves so they dug and dug for ages and ages and they still didn't find the treasure.
