Step 16: Draw the cartoon gorilla's other arm the same way as the first. Start with two long lines. Use quick, short strokes along the bottom for the fur on the wrist. Add a wavy line at the bottom for the knuckles and a U-shaped line on the right for the thumb.
Step 17: Use a series of quick, short strokes between the arm and the leg for the gorilla's leg on the other side. Add the toes at the bottom using a few C- shaped lines.
Step 18: Using a pen or marker, carefully go over the lines to make your cartoon gorilla drawing permanent. After inking, get rid of every pencil mark with an eraser.
Final Step: Color your gorilla drawing using color pencils, markers or even crayons! Use brown for the fur. If you'd like, first use dark brown lightly for a base , then use regular brown over it. Use light brown for the rest of the body and pink or red for the gorilla's mouth and tongue.
