She swam for a while before she arrived at a place built of human bones.
Before she had even knocked at the door she heard the witch’s wicked
voice: “I know why you came!” Then the witch appeared in front of the little mermaid,
“You want to get rid of your fish tail and have legs instead. This is a stupid idea of yours and it will bring you only sorrow,
but you will get your way, since you long for an immortal soul so much.”

“I will prepare a drought for you, which you must drink before the sun rises
tomorrow. Swim to the land, drink it, then you will see how your tail turns
into legs. Of course, you will be in great pain from that moment on and every time you
walk or dance you will feel as if hundreds of sharp knives were cutting
them. You will still have the gracefulness of a mermaid. Can you endure
such pain?” “Yes, I can,” said the little princess, but her voice was trembling. “There is
more. You should know that once your fish’s tail turns into legs, you will no
longer be able to get it back, nor can you return to your father’s castle. You must win the prince’s love and you should get married, so that you can
get an immortal soul. If he marries someone else, your heart will break and
you will turn into foam. Are you sure you want this destiny?”
the witch asked again. “Yes, I do,” answered the little mermaid, pale as the grave. “That’s not all.
You must pay me for this and the price is high. I want your voice as it is the
sweetest voice in the sea kingdom. The prince will not hear your beautiful songs, because I will have to cut your
tongue,” the evil woman continued. “But what is left for me?” said the little
mermaid. “You have your beautiful body, graceful walk, lovely hair and
face. These are enough to enchant a man’s heart. Now stick out your tongue,
so that I can start preparing the draught, which will turn your fish tail into
legs.”
