Under The Sea is kind of a remake of of The Little Mermaid. The plot is there are different kinds of mermaids. A grass, air, water, and psychic. There are two more but they are so rare that they haven't been seen for decades. A Light and Dark Mermaid. Luna is a Dark Mermaid and Owen is a Light Mermaid. Luna loves Owen and Owen loves Luna. But they cannot be together without their parents knowing. As decades ago, a light and dark fairy were together, causing them to fight, as they could never get along. Resulting in a war, nearly destroying the Ocean. Now, Light and Dark Mermaids haven't been seen in over 100 years. Now that Luna and Owen are here, will everything change...?
