"Thousands of years ago, in there left a prophecy that man and nature need to reach a balance, or else a world devastating disaster would occur. Before this catastrophe strikes, man must find the three Keys to each of the Three Worlds to gain the opportunity to save the world. But as history has shown, the balance between man and nature is not an easy thing to achieve. Because they don't always mean it when human and animals cause problems, but they tend to over-exploit and over-use their environment, disrupting the delicate ecological balance and sending the world down the path of destruction. Fortunately, the proud and brave Water Sprite lead their partners to form a powerful environmental task force. They will bravely face this crisis and do whatever it takes to save the wetland world and preserve it for future generations."
