How to draw Plankton

Ahoy, Doodleers! Today we’re zooming in on the tiniest troublemaker in Bikini Bottom—Plankton! This sneaky little villain from SpongeBob SquarePants may be small, but he’s packed with personality (and a serious grudge against the Krusty Krab). In this easy step-by-step drawing guide, you’ll learn how to capture Plankton’s one-eyed scowl, wiggly antennae, and mischievous grin. Perfect for beginners or any SpongeBob fan looking to add a bit of evil genius to their sketchbook.

Grab your pencil—and maybe a Krabby Patty—and let’s get started!

Quick Tip: Always start your drawing lightly with a pencil—this way, you can easily erase any little mistakes, and your final artwork will look clean, neat, and totally awesome!

Step 1

Start with two circles on top of each other.

Step 2

Connect those two circles to create Plankton’s body. Add two little nubs for legs (we bent one to make it look like he’s running). Now add another large circle on the top for his eyeball.

Step 3

Add an eyelid over that new circle. Add a couple of bent points that create Plankton’s antennae and arm. Add the outline of his mouth that covers almost his entire body.

Step 4

Add a pupil in his large eyeball. Add some detail where his eyelid folds. Add a cheek and a little bump where his cheek meets his eyeball. Add some rounded teeth and most of his tongue.

Step 5

Now add the remaining details. Add some lines to his antennae. Add some veins to his bulging eyeball and some tired lines underneath his eyeball. Don’t forget his back arm next to his eye! Then add his throat hole, the remainder of his tongue. Add some spit drops and finally some lip folds near the bottom of his body.

Step 6

Carefully erase all the initial pencil guidelines, leaving a clean, inked drawing of Plankton ready to be colored!

Step 7

Plankton is a very earthy creature with lots of greens for his body and a yellow eye. His mouth is a standard pink tongue and dark red for the inner mouth.

At DoofyDoodles, we love giving our characters a playful spin. Try experimenting with Plankton’s expressions—make him look extra panicked, super angry, or doing his best to steal a Krabby Patty.

Related Questions about Drawing Plankton

Why doesn’t my Plankton look like the one on TV?
That’s totally fine! At DoofyDoodles, we like giving Plankton bigger eyes or a sillier grin. Make him your own version of the tiny troublemaker.

What’s the easiest way to draw Plankton?
Start simple—a tall oval for his body, one big eye, and two antennae. Add arms and legs after the main shape looks balanced.

Can I draw Plankton digitally?
Absolutely! Digital drawing apps make it easy to keep his body perfectly symmetrical and add that glowing green color he’s known for.

Why does Plankton always fail to steal the Krabby Patty formula?
Because that’s what makes him funny! His over-the-top plans (and bad luck) are part of his charm.
