Step 11: On either end of the long line at the bottom, draw a triangle-like shape with a rounded tip for the Goomba's big teeth. Darken the line as you make it wrap around the teeth to finish drawing the mouth.

Step 12: Use the original circle and the arcs on the sides as guides to draw the Goomba's head. Give the shape smooth, rounded lines without any angles.

Step 13: Draw the Goomba's short body under the head by using the initial U shape as a guide. Make the top of the Gooma's body a bit thinner and have the bottom bulge out a bit.

Step 14: Darken the shape of the Goomba's shoes under the body and flatten the bottom part of the shape for the soles of the feet.

Step 15: That’s it! You now have a nice sketch of a Goomba from Nintendo's Super Mario video games. You can stop at this quick drawing for a rough, sketchy look, or continue to the next step to go for a more finished look.
