Fill and Cross Pirate Riddles 3

To sail or not to sail? What kind of question is that?! While others mull it over, you can be the first to find the pirate cache! Somewhere out there, on the bottom of a mysterious lake, lie the secrets of times long past: a crystal capable of giving youth, a cup which can give eternal life with a single sip, and a gold doubloon which brings luck to its bearer… All of this could be yours, if only you get to the island before anyone else! So onwards, summon your crew and set sail! Your journey promises to be risky, but they don’t call you a courageous captain for nothing, right? Go ahead! Hoist the Jolly Roger! Fair winds to ye, sea dog!
