From The Little Mermaid: Yet often, in the evening hours, the five sisters would twine their arms about each other and rise to the surface together. Their voices were more charming than that of any human being, and before the approach of a storm, when they feared that a ship might be lost, they swam before the vessel, singing enchanting songs of the delights to be found in the depths of the sea and begging the voyagers not to fear if they sank to the bottom.
