How can I make a mouse by hand with egg shells

Take a harder egg, (like the sea duck's egg, full of hard) at the bottom, on both sides with a needle (crochet or something) to play two small holes, the egg white yolk poured out, rinsed clean, on both sides through a paper rope, the top of the rope with a small circle wrapped in clay, that is, the hand.

The feet are the same way, but harder to put on some, draw the expression, you can also add some costumes, complete.
