The man-toad

Once upon a time there was a widower, who lived with his three daughters. One day, one of his daughters said to him:
– Father, could you go to the fountain and fetch me a jug of water? There is not a drop left in the house, and I’ll need some for the stew.
– Very well my child, answered the old man.
And he took a jug and went to the fountain. as he was leaning over the water, filling up his jug, a toad sprang up and jumped at his face and clutched at it so tightly that all his efforts to get rid of it were useless.
– You will only be able to get me off your face if you promise to give me one of your daughters for a wife! Said the toad.
He left his jug by the fountain, and ran to the house.
– O God! what happened to you, father? his daughters exclaimed, when they saw him in such a state.
– Alas! my poor children, this animal jumped at my face when I was drawing water from the fountain and now it says that it wil only go away if one of you agrees to marry it.
– Good Lord, what are you saying, father? his elder daughter answered; take a toad for a husband! But it is just hideous!
And she looked away and left the house. The second daughter did the same.
- Well, my poor father, I agree to take it for a husband, because my heart could not suffer to see you stay like this! Said the yougest daughter.
The toad fell to the floor at once. The wedding was scheduled for the following day.
When the bride entered the church, along with her toad, the priest was astonished, and he said that he would never marry a Christian woman to a toad. However, after the father had told him everything and promised him a lot of money, he ended up marrying them.
Then the toad took his wife to his castle – for he had a beautiful castle. When the time had come to go to bed, he led her to his room and there, he took off his toad skin and appeared in the guise of a young and handsome prince! When the sun was over the horizon, he was a toad and at night, he was a prince.
