Use the video and step-by-step drawing instructions below to learn how to draw Sheldon J. Plankton from Nickelodeon's SpongeBob SquarePants. A new cartoon drawing tutorial is uploaded every week, so stay tooned!

Intro: When learning how to draw Plankton, start off with a pencil sketch. In the beginning stages, don’t press down too hard. Use light, smooth strokes for sketching.

Step 1: Start by drawing a small circle near the middle of the page. It doesn’t have to be perfect. It’s just a guide for Plankton’s head. Leave enough room at the bottom for the body and at the top for the antennae.

Step 2: Now draw a circle of similar size under it as a guide for the lower part of Plankton's body. Don't draw this circle too far down or Plankton will end up too long.

Step 3: Draw two lines that connect the two circles to form the guide for the rest of Plankton's body. Bend the lines slightly.

Step 4: Inside the top circle, on the lower, left side, draw a smaller circle as a guide for Plankton's single eye.

Step 5: In the space between the two circles, draw a rectangle as a guide for Plankton's mouth. Notice that the rectangle touches the bottom circle but not the top.
