To Cat, Q, and anyone else that MIGHT care.
You don't have to "draw" anything. It's such a small picture, that all you'd have to do, is change the color of the pixels(almost all digital images are made up of squares, called pixels).
In other words, there are only four dots(squares) that make the eye of these smilies(most of them, anyways), change the four black dots(squares) to four red dots, you have a red-eyed smiley. Simple.
P.S. Try the non-animated smileys first.
