Riddle game

You’re strong, and I can now clearly see it. Now show me how clever you are. I will tell you three riddles, and you are to bring me the answers to the riddles.

First riddle. I have scissors for hands and I walk sideways.

Second riddle. I have a little house in which I live all alone. It has no doors or windows, and if I want to go out, I must break through the wall.

Third riddle. White horses stand on a red hill, first they champ, then they stamp, then they stand still.

If you are smart enough, you can guess what it is! Otherwise, you’re not worthy of seeing the Queen!
