Step 6: Under the body, draw two small lines for Mr. Krabs' feet. His crab feet are tiny, so don't draw these lines too long.
Step 7: That’s it for the initial sketch! You have the basic shape of Mr. Krabs from Nickelodeon's SpongeBob SquarePants. Now go in and tighten your drawing. From this point on, press harder with your pencil in order to get darker lines and a more defined sketch.
Step 8: Now learn how to draw Mr. Krabs' eyes. First darken the shape of the eye guides. Follow the basic path of the two arcs and bend the lines more. The crab's eyes should be wide at the top and thinner at the bottom.
Step 9: Inside each eye, draw a small oval and shade it in for the pupils. At the top of each eye, draw three tiny arcs for the detail atop Mr. Krabs' eyes.
Step 10: Now learn how to draw Mr. Krabs' mouth. First draw two lines sitting on top of the original oval and underneath the eyes. The lines should start near the left eye, and then split off and curve down and to the right to create this crab cartoon's open mouth.
