If you can draw a rectangle, you can draw SpongeBob SquarePants! Don't get complicated and create a basic outline for this cartoon character that everyone loves. Add her arms and legs before drawing her collar and tie. Once you have drawn your favorite sponge, go back over the drawing to color it the way you want.
Steps
Part 1 of 2: draw the body of SpongeBob SquarePants

Step 1. Draw a vertical rectangle with wavy edges
Draw a rectangle the size you want for SpongeBob's head. Draw the longer sides about one and a half times longer than the shorter horizontal lines. Instead of drawing it with straight edges, instead make wavy and jagged lines.
- The head should be slightly narrower at the bottom than at the top.
- The wavy rectangle should roughly resemble a sponge.

Step 2. Sketch a rectangle at the bottom of the main rectangle
To draw SpongeBob's torso, draw a vertical line that goes down either side of the rectangle. These lines should be about a quarter of the length of SpongeBob's head. Then draw a straight horizontal line to connect the vertical lines.
Leave the wavy line at the bottom of the head, where it touches the torso
Variation:
draw a narrow rectangle that protrudes from the right edge of SpongeBob SquarePants if you want to draw it in 3 D. Draw a rectangle that becomes narrower away from the middle of SpongeBob SquarePants.

Step 3. Draw a collar and tie in the center of the lower rectangle
For the collar, draw two V-lines along the bottom wavy line of the head. Leave a V-sized space in between. Next, draw a semicircle between the two V-shapes and draw the pointed tie protruding from the bottom of the torso.
For the tie, you just need to draw a vertical rhombus from the bottom of the semicircle to the bottom of the torso

Step 4. Draw a straight horizontal line with four rectangles
This will be the pants. Take a ruler to draw a straight line down the middle of the torso. Avoid going through the tie and go back to erase the line if they overlap. For the belt, sketch four thin rectangles below the waist and shade them. Make two rectangles on each side of the tie and leave a space between each.
Each space should be a quarter of the size of the rectangle

Step 5. Make the legs
Draw two rectangles and long vertical lines. For the bottom of the pants, draw two small rectangles that protrude from the bottom of the waist. They should be about half the length of SpongeBob's pants. Leave a space the same size as the rectangle in between. Next, draw two vertical lines protruding from each pant leg to make a very thin leg.
Each leg should be as long as the torso

Step 6. Draw a horizontal line for the sock
Draw a short horizontal line halfway down the leg to connect with the vertical lines on the leg. To add detail to the sock, draw two more horizontal lines across the top to make stripes.
If you are going to color your drawing, you can add a red stripe at the top and a blue stripe at the bottom

Step 7. Draw a horizontal figure eight for the shoe
Draw two horizontal circles connected at the bottom of the leg. Shade the circles for a dark colored shoe. Next, draw a small square at the base of the shoe for the heel.
Repeat the same steps on the other side

Step 8. Draw the sleeves up to the fingers
Draw a small sleeve about the same size as the pant leg protruding from the bottom of the head. Curve it away from the head and draw a horizontal line that meets the wavy line at the bottom of the head. For the arm, draw two vertical lines that come out from the middle of the sleeve to the waist. Next, draw a four finger hand, keeping each finger curved and exaggerated.
Follow the same steps on the other side of SpongeBob's body
Part 2 of 2: draw the face of SpongeBob SquarePants

Step 1. Draw two large circles in the center of the head
Imagine a horizontal line running across SpongeBob's head. Make two large circles in the middle of the head, making them touch each other. Draw each circle so that it almost fills the top quarter of the head. Then draw a medium circle inside the eye to make the iris and draw a smaller circle for the pupil.
Shade the pupil until it is black and do not touch the iris, as it will be blue

Step 2. Draw three straight lines on top of each eye
To make SpongeBob's eyelashes, draw a short line that protrudes from the top of each eye halfway to the top of the head. Then draw another short line next to it curving it outward from the head. Draw the third by curving it in the opposite direction.
Remember to leave space between each lash so that they occupy the entire upper part of the eye

Step 3. Give her a big smile
Place the pencil between the left eye and the side of SpongeBob's head. Draw a line from this point curving towards the center and going up to the opposite side of SpongeBob's head. To make the dimples, draw an arc above the ends of the smile.
To make the dimples stand out better, draw a wider arc over the ends of the smile
Advice:
if you want to add more detail to it, add three dots to each dimple near the smile.

Step 4. Draw a curved nose under the eyes
Place the tip of the pencil at the bottom of the left eye. Make it go up on the right, then go down on the left in a single gesture. This will create a round nose that overlaps the right eye and goes below the starting point of the nose.

Step 5. Draw two rectangles for the teeth
Also draw a wavy line below for the chin. Draw two vertical rectangles that protrude from the bottom of the smile. Make teeth the same size as the nose and leave a space between the teeth to make them stand out. Then continue with a wavy line underneath that runs from one end of the teeth to the other.
The wavy line will give the appearance of a chin

Step 6. Draw ovals on the head for a spongy appearance
Trace them without pressing and make them in different sizes all over the head. Put some near each other and make others further away. Leave the ovals clear or shade them lightly so they look like holes in SpongeBob SquarePants.
