I saw that easing variable was added, but no easing code was included so that easing happened. so, I modified the first few lines of function draw () to make easing happen:

```auto
function draw() {
  var targetX = mouseX;
  x += (targetX - x) * easing;
  var neckY = -1 * (bodyHeight + neckHeight + radius);
  background(204);
  translate(x, y); // Move all to (mouseX, y)

```

Is that a page number from Getting Started With p5.js?
