Kakoa watched the girl, his blue green tail cutting through the water. His tail fins were long and flowy like that of a koi fish. In the sunlight his tale would catch the light and shine with the pearl-essence one sees on the inside of a sea shell. It was a shimmer of blues and greens and golds. Kakoa watched the girl, wanting to approach but knowing in his merman form that wasn't safe. His tail flicked in irritation at his train of thoughts, causing a soft splash that he didn't even notice.
