The actual way to approach these characters without overcomplicating it
The first thing most people get wrong is starting with the face details. You should be building the geometry first, then refining, not the other way around. Spongebob's entire structure is built on rectangles and ellipses, which sounds obvious but people ignore that and start drawing eyes before they've got the yellow block in proportion. That leads to the classic wobbly, off-center result that looks nothing like the show. I spent a bunch of time going through this method with a few kids in an after-school program and what I noticed was consistent: everyone wanted to jump straight to the details because the characters are so iconic. They knew what Spongebob looked like but had no idea how to translate that into a drawing from scratch. The workaround was making them draw the box first, lightly, with a ruler even, and then rounding the corners gradually. Once the rectangle was correct, everything else fell into place much faster.
How To Draw Spongebob And His Friends
Start with a light vertical center line and a horizontal line about a third of the way down from the top. That gives you your eye placement guide. Then sketch a large rectangle. Spongebob isn't perfectly square, he's more of a wide rectangle with rounded corners, roughly 1.2 times wider than he is tall. Use your center lines to place the eyes evenly, the mouth below that, and the pants line at the lower third. For the eyes, draw two large ovals on the upper half. Spongebob's eyes are characteristically huge compared to his face, taking up about half the upper rectangle. Inside each eye put a circle for the iris and pupil, slightly offset toward the center for that iconic wide-eyed look. The eyebrows are simple horizontal lines just above the eyes. His mouth is a wide smile that curves up at both ends. The teeth are two rectangular blocks in the center, slightly larger than the teeth of most cartoon characters. Add the dimples at the corners and a single nostril dot inside each of the two large oval nose holes just above the mouth.
The shirt collar comes just below the main face rectangle, two small triangular points. The tie is a simple triangle hanging down, and the pants start below that. His legs are two thin cylinders ending in shoes. Keep the proportions loose at this stage.
Get the Full Details

Patrick Star is simpler than people think
Patrick's body is essentially a pear shape or a teardrop pointing upward. That's it, mostly. Start with a large circle for the head and an oval beneath it for the body, connecting them smoothly. His five fingers are just five small ovals coming off the sides where his arms would be, drawn without separate arm lines. The eyes are small triangles set wide apart with tiny pupils. His signature goofy grin is a simple curved line with two teeth showing. The whole character is roughly the same height as Spongebob but wider and shorter, which is why people mess up the proportions when they try to draw them together in a scene. Squidward is where a lot of people struggle because the character has so many organic curves compared to the geometric simplicity of Spongebob. Start with an oval for the head, which is distinctly bulbous and larger than the rest of his body. His nose is that prominent long oval that extends well below the face line. The eyes sit in the upper portion, each with a single eyelid curve giving him that perpetually unimpressed expression. His body tapers downward into a tapered torso, and his six tentacles are thick at the base and thin out toward the ends, each with a slight curve, not straight lines. The key detail people miss is the three pores on his nose. Small circles, evenly spaced, and they make the difference between a generic squid character and Squidward. The biggest time sink I see is people redrawing the same character five or six times because the initial construction lines were too dark to erase later. Use a light hand with your pencil, or if you're working digitally, put construction lines on a separate layer underneath everything. This can cut your revision time down significantly because you're not hunting for stray lines every time you change your mind about a proportion. Another thing, and this is something I learned the hard way: don't trace reference images directly if you're trying to actually learn the drawing process. It gives you a passable result in ten minutes but teaches you nothing about how the shapes fit together. If you're short on time and just need an image, tracing is fine, but it won't make you better at drawing these characters independently.
There's also the issue of color choice. Spongebob yellow is specific. It's not a standard bright yellow, it leans slightly toward a warm butter or marigold tone. Using the wrong yellow makes the character look off even if the drawing itself is accurate. If you're coloring digitally, a hex around #FFFF99 to #FFD966 range usually works, depending on whether you want it more lemon or more golden. Patrick's pink is similarly specific, more of a salmon or watermelon pink rather than a hot pink.
What doesn't work well
Trying to draw all the characters at full complexity in one sitting rarely goes well. Their designs are deceptively simple, and when you add every detail correctly, it takes longer than you'd expect. A decently detailed Spongebob at a medium resolution will take about twenty to forty minutes if you know the proportions well, but closer to an hour or two on your first few attempts. The method described here gets you there faster, but don't expect to nail the facial expression work on the first try. The eyes especially require adjustment because getting them symmetric while maintaining the slightly asymmetrical charm of the original design is trickier than it sounds. If you find yourself getting frustrated with this approach, switch to studying individual features separately, spending a session on just eyes, then just mouths, then full faces. That's how I reorganized my practice when I hit a wall with the character expressions.
