Draw two ovals like this.

Then draw a carrot shape under neath the ovals.

Then put pupils in the eyes so the eyes will be finished.

Then you draw the crooked smile or any other smile you would like in the carrot shape.

Next you draw the body with an oval shape in the inside.

After that you draw the feet.

And this step is optional but you can color it in to add some color to it.

Hope this helped all of you who didn't know how to draw a penguin. :)
