But she was mistaken; for when night came again she heard the same tapping at the door; and the frog came once more, 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.'
And when the princess opened the door the frog came in, and slept upon her pillow as before, till the morning broke.
