var Animal = Object.create({

  	console.log('walking');

var sunny = Dog.create({name: 'Sunny'});

console.log(sunny.name);

That's pretty close to the native version of Object.create and offers currying of the previous object's create method.

if (typeof Object.create !==
 "function") {
  Object.create = function (object) {
    function F() {}

    F.prototype = object;

    return new F();
  };
}
