Journey on a Pirate Ship

On this journey on a pirate ship, we are in the backyard in the sand box. I'm traveling the world on a solo mission trying to find the last island of Atlantis. Legend has it that the lost city of Atlantis has a special power crystal that powers the whole island and is more powerful that anything in the universe. I need to get to the crystal fast because if it gets into the wrong hands then it can mean devastation for the world. WISH ME LUCK !
