Step 11: Starting at the bottom of Gary's shell, draw a line that curves up and swirls in the middle for the shell's design. Sketch lightly at first so that its easy to erase if you make a mistake. Darken the line only when you get the shape right. Make the tip of the swirl pointy. Don't curve the spiral too much. Just a simple single curve will do. Don't make the shape too thick. The end result should be similar to the letter P or an upside-down 6.
Step 12: Draw five small ovals along the top side of Gary's shell to finish the design. The top-most oval should be bigger than the four ovals on the sides.
Step 13: Using a pen or marker, carefully draw over the lines to make your Gary drawing permanent. After inking, get rid of every pencil mark with an eraser.
Final Step: Color Gary from SpongeBob SquarePants using colored pencils, markers or crayons! Use yellow-green for the eyes and bottom of the body. Use orange for the irises and light blue for the rest of Gary's body. Color the main part of the shell pink. Don't overlap the design! Color the ovals bluish-purple and the spiral dark red. Don't forget to pause the video after each step to draw at your own pace.
