Water gem

The water gem holds the power of water. It was made at the bottom of the sea. The way that happened is when a crystal got stuck down there for millions of years. A penguin named Hydro found the gem first. But he was lost forever at the sea. And the gem was found by the ultimate ninja master. And he built the amulet for it. Many fake gems have been in creation at the near the bottom of the sea for years. They are not as strong, but still powerful. And that's all that matters.
