As soon as the young princess saw her ball, she ran to pick it up; and she was so overjoyed to have it in her hand again, that she never thought of the frog, but ran home with it as fast as she could.
The frog called after her, 'Stay, princess, and take me with you as you said,'
But she did not stop to hear a word.
The next day, just as the princess had sat down to dinner, she heard a strange noise - tap, tap - plash, plash - as if something was coming up the marble staircase, and soon afterwards there was a gentle knock at the door, and a little voice cried out and said:
'Open the door, my princess dear,
Open the door to thy true love here!
And mind the words that thou and I said
By the fountain cool, in the greenwood shade.'
Then the princess ran to the door and opened it, and there she saw the frog, whom she had quite forgotten. At this sight she was sadly frightened, and shutting the door as fast as she could came back to her seat.
