These passages are from the Anderson original. His mermaid was the most captivating dancer there ever was, so if this is what they’re gonna go with for the show, JoAnna best get her two left feet fixed. 😉
Your tail will then disappear, and shrink up into what mankind calls legs, and you will feel great pain, as if a sword were passing through you. But all who see you will say that you are the prettiest little human being they ever saw. You will still have the same floating gracefulness of movement, and no dancer will ever tread so lightly; but at every step you take it will feel as if you were treading upon sharp knives, and that the blood must flow.
The slaves next performed some pretty fairy-like dances, to the sound of beautiful music. Then the little mermaid raised her lovely white arms, stood on the tips of her toes, and glided over the floor, and danced as no one yet had been able to dance. At each moment her beauty became more revealed, and her expressive eyes appealed more directly to the heart than the songs of the slaves. Every one was enchanted, especially the prince, who called her his little foundling; and she danced again quite readily, to please him, though each time her foot touched the floor it seemed as if she trod on sharp knives.
