Step 16: Now learn how to draw Mr. Krabs' pants and feet. Use the bottom part of the original oval and the tiny lines to draw his pant and feet. Darken the sides of the oval and draw the pant cuffs at the top of the feet. Draw the little stumpy crab feet below the pant cuffs using the small lines as guides.

Step 17: Draw the detail of Mr. Krabs' pants inside the original oval shape. Draw a rectangle-like shape near the top for his belt buckle. Draw a couple more rectangle-like shapes on either side of the buckle for the actual belt. Under the belt buckle, draw a small arc for the zipper cover on his pants.

Step 18: That’s it! You now have a nice sketch of Mr. Krabs the crab from the Nickelodeon cartoon SpongeBob SquarePants. You can stop at this quick drawing for a rough, sketchy look, or continue to the step below to go for a more finished look.

Step 19: For a more finished, inked look, carefully draw over the final sketch lines with a pen or marker. Wait for any ink to dry, and then erase your pencil marks. You now have a finished inked drawing of Mr. Krabs! You can stop here or go to the final step to complete your Mr. Krabs drawing in its entirety.

Final Step: For a completely finished Mr. Krabs drawing, you have to color it. You can use anything you want: markers, color pencils or even crayons! Color the main part of Mr. Krabs' body red. His eyes are light yellow, the inside of his mouth is brown, and his tongue is pink. His shirt is light blue, his buckle is yellow, his belt is black, and his pants are a blueish purple. That’s it! You now have a completed drawing of Mr. Krabs, the greedy crab who owns the Krusty Krab restaurant where SpongeBob SquarePants works.
