Blurry Animation

Whenever I save the image, it comes out as blurry.

So, I was working on an animation that was supposed to be all reto-pixely. So the image is only 40x40. But when I go to save it as a .gif, the animation comes out as really blurry, and I can't find out how to fix this.

Please comment your answers down below. I would really appreciate it. Thanks in advance!
