How to Draw Keroppi: The Complete Step-by-Step Tutorial for Beginners and Beyond
If you’ve ever found yourself completely charmed by a tiny green frog with an oversized smile and the most optimistic energy in all of Sanrio, then you already know exactly who Keroppi is. This beloved character has been capturing hearts since his debut in 1988, and today he’s more popular than ever — showing up on everything from tote bags and phone cases to fan art feeds and, yes, YouTube tutorials. Whether you’re a complete beginner who has never drawn a cartoon character before or an experienced artist looking to add Keroppi to your repertoire, this guide is going to walk you through everything you need to know.
This tutorial is designed to complement a full video walkthrough on YouTube, so you can follow along at your own pace, pause when you need to, and come back to these written steps whenever you want a quick reference. Let’s dive in.
Who Is Keroppi? A Quick Introduction Before You Draw
Before you put pencil to paper, it helps to understand who you’re actually drawing. Keroppi — full name Koroppi, though he’s almost universally known by his nickname — is a small frog who lives in Donut Pond, just outside the city. He’s cheerful, adventurous, and has a slightly mischievous streak that makes him endlessly lovable. His defining visual features are his enormous, wide-set eyes, his big happy mouth that takes up a significant portion of his face, and his distinctively striped body.
Unlike many Sanrio characters, Keroppi has an incredibly expressive face. His design is built around that smile — it’s huge, it’s genuine, and it practically radiates joy. Understanding this helps you draw him more authentically, because you’re not just copying shapes; you’re capturing a mood.
Supplies You’ll Need for This Tutorial
One of the best things about learning to draw Keroppi is that you really don’t need anything fancy to get started. Here’s what the YouTube tutorial uses, and what you can substitute if you don’t have everything on hand.
For traditional drawing, you’ll want a pencil (an HB or 2B is ideal for sketching), a good eraser, a black fine-tip pen or marker for inking, and colored pencils, markers, or watercolors for filling in the final piece. Keroppi’s signature colors are a warm grass green for his body, a pale cream or white for his belly area, and red for his iconic collar or shirt. His eyes are large, dark, and expressive, often with a small white highlight dot to give them life.
If you prefer digital drawing, the same principles apply. Use a sketching layer, a clean inking layer, and separate color layers. Procreate, Adobe Fresco, and even free apps like Medibang Paint work beautifully for this kind of character illustration.
Understanding Keroppi’s Basic Shape Language
Every cartoon character is built on a foundation of simple geometric shapes, and Keroppi is no exception. Before you try to draw him in one confident go, it really pays to spend a few minutes just understanding the shapes that make him up.
His head is essentially a large circle or oval, slightly wider than it is tall. This is the dominant shape in his design — everything else is relatively small compared to that big round head. His body, when visible, is a smaller rounded shape beneath the head, almost like a shorter, squatter oval. His arms are small and tend to stick out with that classic froggy energy, slightly bent at the elbows. His legs are similarly proportioned — short, rounded, and often tucked under him or positioned in a way that suggests he’s ready to leap.
His eyes are two large circles placed fairly high on his head and quite wide apart. This wide eye placement is crucial to capturing the Keroppi look. Between and below the eyes, you have a very small, almost button-like nose, and then that magnificent mouth — a wide, arching curve that often sweeps across the entire lower portion of his face.
If you can sketch a large circle, two smaller circles for eyes, and a wide curved line for a mouth, you already have the skeleton of a Keroppi drawing. Everything else is detail work.
Step-by-Step Drawing Instructions
Step 1: Sketch the Head Shape
Start by drawing a large, lightly sketched circle in the center of your paper. Don’t press hard — this is just a guide that you’ll eventually erase or refine. Make the circle as round and even as you can. If it helps, you can trace a circular object or use a compass, but freehand is perfectly fine and actually gives the drawing a warmer, more handmade feeling.
Leave plenty of space below the circle for the body, and a little space above it if you plan to add any background elements or a title text later.
Step 2: Add the Eye Guidelines
Draw a light horizontal line across the upper-middle portion of your circle — somewhere between the center and the top. This is your eye line. Keroppi’s eyes sit relatively high on his head, which contributes to his wide-open, expressive look.
Now place two evenly spaced marks on either side of the center, fairly far apart from each other. These marks will be the centers of his eyes. Take a moment to make sure they feel balanced — uneven eyes are the most common issue when drawing cartoon characters for the first time, and a quick check before you commit saves a lot of frustration.
Step 3: Draw the Eyes
At each of those center marks, draw a large circle. Keroppi’s eyes are bold and prominent — don’t be afraid to make them bigger than feels comfortable. They should take up a significant amount of real estate on his face.
Inside each eye circle, draw a slightly smaller filled-in circle for the iris and pupil (in Keroppi’s style, these are often combined into one large dark shape). Then, add a small white circle in the upper portion of each eye — this is the highlight, and it’s what gives his eyes that sparkly, lively quality. You can leave this area white when you color, or add it in at the end with a white pen or white paint.
Along the top of each eye, you can add a subtle thickening of the line or a small eyelid curve to give the eyes a little more dimension and personality.
Step 4: Add the Nose
Between and just below the eyes, draw a very small oval or two small oval dots side by side. Keroppi’s nose is intentionally minimized — it’s almost an afterthought compared to those enormous eyes and that wide smile. Don’t overthink this step. A tiny mark is all you need.
Step 5: Draw the Mouth
This is the most important and most fun step. Starting from below and slightly outside the left eye, draw a long, wide, arching curve that sweeps all the way across the lower portion of the face and ends below and slightly outside the right eye. This smile is enormous and genuine — it should feel like it takes up the whole bottom half of the face.
Many Keroppi illustrations also show the interior of the mouth slightly, with a short curved line representing the edge of the lower lip or tongue area. You can add this or keep the smile as a simple open curve — both look great, and it largely comes down to what style you prefer.
Step 6: Sketch the Body
Below the head, draw a smaller rounded oval shape. Keroppi’s body is often partially hidden by his head when he’s drawn in a typical sitting or standing position, so this shape can be quite small. It should feel like it tucks naturally under the chin area of the head circle.
If you’re drawing him from the front in a sitting position, the body can be almost entirely obscured, with just the lower portion visible below the chin. If you want to draw him from a slight angle or in a more dynamic pose, give the body a little more room to breathe.
Step 7: Add the Arms
From either side of the body, sketch two short, rounded arms. Keroppi’s arms have that classic cartoon frog shape — a little stubby, slightly curved at the elbow, with small, rounded hands or mitten-like fingers. You can position them however feels natural to the pose you’re going for: arms at his sides, raised in greeting, or holding something like a leaf or a little heart.
Step 8: Add the Legs and Feet
At the base of the body, add two short legs and rounded feet. Keroppi’s feet are somewhat large relative to the rest of him, which is a charming design choice that reinforces his frog identity. If he’s sitting, his feet can peek out from under his body. If he’s standing, his legs will be more visible — short, slightly bowed, with those round feet planted firmly beneath him.
Step 9: Add the Collar or Shirt Detail
One of Keroppi’s most recognizable accessories is his little striped shirt or collar — typically red and white. Add a curved collar line at the base of his neck where the head meets the body, and then a few horizontal stripes on the visible portion of his body. These stripes are simple parallel curves that follow the rounded shape of his torso.
Step 10: Refine and Ink
Go back over your sketch with a fresh eye. Look at the proportions: is the head large enough? Are the eyes wide-set and expressive? Does that smile feel as big and joyful as it should? Make any adjustments now, before you commit to inking.
Once you’re happy with the sketch, go over your final lines with a black pen or fine-tip marker. Work steadily and confidently — try not to trace every wobbly pencil line, but instead draw the cleaner, more resolved version of each shape. Let the ink dry completely before erasing the pencil underneath.
Step 11: Add Color
Now comes the most satisfying part. Fill in Keroppi’s body with his signature green. The shade should be warm and mid-tone — not too yellow, not too dark. His belly area can be left lighter or filled with a pale cream. His collar and shirt stripes go in red. His eyes should be deep and dark, with those white highlight dots reserved.
Add a little shading if you want depth — a slightly darker green on the sides of the body and under the chin gives the drawing a more three-dimensional feel without complicating it. A gentle blush circle on each cheek, added with a light pink, can give Keroppi an extra dose of cuteness that fans of the character will immediately recognize.
Common Mistakes and How to Fix Them
Even experienced artists run into the same stumbling blocks when drawing Keroppi for the first time. The most frequent issue is making the eyes too small or placing them too close together. If your Keroppi looks a little off and you can’t figure out why, check the eyes first — they’re almost always the culprit.
Another common mistake is making the smile too small or too timid. Keroppi’s whole personality lives in that enormous grin. If it doesn’t feel a little exaggerated, it probably isn’t big enough yet.
Getting the head-to-body ratio right can also take a few tries. New artists often instinctively make the body bigger than it should be, which throws off the whole character’s proportions. Remember: the head is the star of the show, and the body is just there to support it.
Tips for Developing Your Own Keroppi Style
Once you’ve got the basics down, the real fun begins — making Keroppi your own. Many artists who love Sanrio characters develop their own personal spin on the character while keeping the core design recognizable. You might experiment with different expressions (a surprised Keroppi, a sleepy Keroppi, a Keroppi mid-leap), different poses, or even seasonal outfits and accessories.
Drawing Keroppi in different settings is another wonderful creative exercise. Imagine him sitting on a lily pad, peeking out from a teacup, or surrounded by his friends from the Donut Pond universe. Every new context gives you a new set of drawing challenges and helps you grow faster than simply repeating the same pose over and over.
Why YouTube Is the Best Place to Learn to Draw Keroppi
Written tutorials are invaluable for reference, but there’s a reason the YouTube tutorial format has become so beloved in the art learning community. Watching someone draw in real time — seeing how they build up shapes, how they correct mistakes, how their hand moves — teaches you things that words and static images simply can’t convey. You can pause, rewind, and slow down a video in ways that a traditional art class doesn’t allow.
The comments section of a Keroppi drawing tutorial is also a genuinely lovely community space. Artists of all skill levels share their finished work, offer encouragement, and ask questions. If you’re feeling nervous about starting, watching a few of these videos first and seeing the wide range of artwork people create — from wobbly first attempts to incredibly polished finished pieces — is often all the motivation you need to pick up a pencil.
Practicing Beyond the Tutorial
The tutorial is just the beginning. The artists who improve the fastest are the ones who practice consistently — not necessarily for long stretches of time, but regularly. Even spending fifteen minutes a day sketching Keroppi in different expressions or poses will lead to dramatic improvement over the course of a few weeks.
Try keeping a small sketchbook dedicated entirely to Sanrio characters. Draw Keroppi every day for a month and watch how much your confidence and skill level evolve. By the end, you’ll be drawing him from memory, in any pose, with barely a second thought.
Share your work as you go, whether that’s posting to social media, tagging the original tutorial creator on YouTube, or just showing friends. Getting your art out into the world, even in small ways, is part of the process and brings a genuine sense of accomplishment and community.
Final Thoughts
Keroppi is one of those characters that makes people happy just by existing — and there’s something really special about learning to draw a character who carries that much joy. Whether you’re following along with the YouTube tutorial for the first time tonight or coming back to this written guide for a quick refresher, the most important thing is that you enjoy the process. Art is supposed to feel good, and drawing a smiling frog who lives in a pond called Donut Pond should feel like exactly the kind of whimsical, lighthearted creative adventure it is.
So grab your pencil, pull up the video, and let’s draw Keroppi together. That big grin is waiting for you.
