The Story of the Frog Prince (Describing is more of summarizing and giving your own opinion on something, what you are doing in this entry is more of telling a story.)

Once upon a time, there lived a king and his daughter in the castle.
One day, the princess took the golden ball and played by the pond in the forest. Suddenly, the ball fell into the pond by mistake.Then, she began to cry, and cried louder and louder.
“Why are you weeping, princess?” said the frog who was sitting on the stone.
The princess looked around and just found a disgusting frog .
“My favourite golden ball has fallen into the pond, and I can’t get it,” she said with tears.
“You need not weep,” said the frog.”I think I can help you, but you must kiss me if you want me to get your ball.”
The princess reluctantly consented to the frog. So, the frog jumped into the pond. In a short while, he carried the ball to the surface, and threw it onto the grass. The princess was overjoyed and took it away.
“Wait! Wait! Princess, you must kiss me,” the frog shouted. But she pretended not to hear him.
Next day, the frog hoped up to the castle door.
“Lovely princess, open the door please!”
The princess went to the door and found the lousy frog, she was frightened by him and slammed the door.
“Oh, dear, what’s the matter?” asked the king.
And the princess told him about what happened in yesterday. Then, the king reminded his daughter that she must keep her promise, "Go and let the frog in at once."

The frog jumped upon the table and ate with princess.
At last, the frog said that he has eaten and drunk quite enough. It’s time to sleep with princess. When the princess heard that, she weeped again. She can’t stand the disgusting frog. But the king was displeased at her tears. The king emphasized that she keep her promise. When they went to the bedroom, the frog crept out of his corner and said to princess, “You must give me a kiss or I will tell your father.” The princess was angry to hear that, and she grabbed the frog and threw him against the wall. But soon, she found the frog would not stir. She felt regret about hurting him. She held him in the palm of her hand, and gave him a kiss. Suddenly, with a bright flash, the spell was broken. The frog had changed into a handsome prince.
Afterwards, the prince told the princess about the spell by the witch.
And the prince and princess lived happily ever after.

The other corrections I made mostly had to do with proper grammar, spelling, and punctuation, such as using commas before a " mark to indicate the end of a sentence that someone is speaking, and using spaces    after a comma , and a period . , not before. Otherwise, your entry was very good. Keep up the good work!
