Rumpelstiltskin

I read "Rumpelstiltskin" , Usborne Young Reading, level 1 book.

This title is a dwarf's name.
One day a beautiful and poor girl met a prince by chance.
Her father told a lie to him that she can generate a gold from straw.
He take her to castle and to put her into a room which are a lot of straw to confirm what her father said.
When she was crying, a dwarf came to help her .
He helped her but he demanded her the alternative.
So she told to give him a baby who will born in the future...　
In the middle of the happiness, he is trying to deprive a baby of her.
If they find his name, they will be able to hold a baby.
Wii they be able to hold their baby?

This story is very scared because a dwarf was a very bad man.
They found that his name was "Rumpelstiltskin" at last!
It is very long and difficult to pronounce.
I think that the prince is also a bad man because he let her knit gold from straw in vain a lot.
It is not the true happiness!
