But the oldest little goat thought of what his mother had said.

"If you are our mother, put your foot on the window sill, that we may see it."

When the wolf had done this, all the little goats cried out, "No, you are not our mother. We shall not open the door. Our mother's feet, are white and yours are black. Go away; you are the wolf."

Then the wolf went to the miller's, and said to him, "Mr. Miller, put some flour on my foot, for I have hurt it."

The miller was so afraid of the wolf that he did as he was told.

Then the wicked wolf went to the goat's house again and said, "Open the door, dear children, for I am your mother."

"Show us your foot," said the little kids.

So the wolf put his one white foot on the window sill.

When the little kids saw that it was white, they thought this was really their mother, and they opened the door.
