The marine world is diverse and magnificent. You can watch the movement of the fish for hours, jiggling jellyfish and steaming electric rays. But in addition to the underwater beauties, many are also attracted by the treasures of the drowned ships. Barbara, the heroine of the history of Ocean Mystery, has been diving since childhood. She descended to great depths and feels almost a member of the maritime community. The girl leaves on the boat and sinks under the water. Once, once again exploring the ocean floor, she discovered the ship. It was almost half filled with sand and was not visible. Having worked a shovel a little, the heroine discovered many different objects, utensils, ornaments, many of which can become a valuable find.
