Easy-to-Follow Instructions for Handmade Crochet Platypus Amigurumi

If you’ve ever wanted to crochet something that is equal parts adorable and unexpected, a platypus amigurumi might be exactly what you’ve been looking for. With its signature duck-like bill, wide flat tail, and plump little body, the platypus is one of nature’s most charmingly strange creatures — and it translates beautifully into the world of amigurumi. Whether you’re an intermediate crocheter looking for a new challenge or a confident beginner ready to level up your skills, this guide will walk you through everything you need to know to create your very own handmade crochet platypus.

Let’s dive in.

What Is Amigurumi?

Amigurumi is the Japanese art of crocheting or knitting small stuffed animals and characters. The word itself is a combination of the Japanese words “ami” (knitted or crocheted) and “nuigurumi” (stuffed doll). These little figures are worked primarily in the round using single crochet stitches, which creates a tight, smooth fabric that holds stuffing well and shows off the round, three-dimensional shape that makes amigurumi so recognizable.

The platypus is a wonderful amigurumi subject because its distinctive body parts — the wide bill, webbed feet, beaver-like tail, and rounded body — all translate naturally to the curves and rounds of crochet construction. Once you understand the basic technique, you’ll find that building a platypus is simply a matter of assembling several individually crocheted pieces into one incredibly endearing little animal.

Materials You Will Need

Before you start crocheting, gather everything you’ll need so the process goes smoothly from start to finish.

Yarn: You’ll need a medium weight (worsted weight, size 4) yarn in the following colors. For the main body, choose a warm brown or a medium brownish-gray to mimic the platypus’s natural coloring. You’ll also want a lighter beige or cream color for the underbelly and bill, and small amounts of dark brown or black for the eyes if you plan to embroider them rather than use safety eyes.

Hook: A 3.5mm or 4mm crochet hook works well with worsted weight yarn for amigurumi. You want your stitches to be tight enough that the stuffing doesn’t show through, so go down a hook size from what the yarn band recommends if needed.

Safety eyes: A pair of 9mm or 12mm black safety eyes will give your platypus that classic amigurumi look. If you’re making this for a child under three years old, embroider the eyes with black yarn instead, as safety eyes can pose a choking hazard.

Polyester fiberfill stuffing: A good-quality fiberfill will give your platypus a pleasingly plump shape. Don’t skimp on stuffing — firmly stuffed pieces hold their shape much better over time.

Yarn needle: A blunt tapestry or yarn needle is essential for sewing the pieces together and weaving in your ends.

Stitch markers: These are invaluable in amigurumi for keeping track of the beginning of each round.

Scissors: Any sharp pair will do.

Optional wire armature: If you’d like your platypus to be poseable, you can insert a small pipe cleaner or floral wire frame into the legs and tail before closing them up. This is entirely optional but adds a fun interactive element.

Gauge and Sizing

Using a 4mm hook with standard worsted weight yarn, the finished platypus will measure approximately 7 to 8 inches from bill tip to tail end and stand about 3 to 4 inches tall when sitting. If you prefer a smaller figure, switch to a lighter weight yarn and a correspondingly smaller hook. If you want something larger and more huggable, try bulky weight yarn with a 5mm or 6mm hook.

Crochet Platypus Pattern Instructions

Part One: The Body

The body is the largest piece and the foundation your other parts will attach to, so crochet it first and set it aside while you work on the remaining pieces.

Start with your main brown yarn.

Rnd 1: MR, 6 sc in ring. Pull tail to close the ring. (6 sts)
Rnd 2: Inc in each st around. (12 sts)
Rnd 3: [Sc 1, inc] x 6. (18 sts)
Rnd 4: [Sc 2, inc] x 6. (24 sts)
Rnd 5: [Sc 3, inc] x 6. (30 sts)
Rnd 6: [Sc 4, inc] x 6. (36 sts)
Rnd 7: [Sc 5, inc] x 6. (42 sts)
Rnds 8–16: Sc around in each st. (42 sts) — work 9 rounds even.
Rnd 17: [Sc 5, dec] x 6. (36 sts)
Rnd 18: [Sc 4, dec] x 6. (30 sts)

Before you continue decreasing, insert your safety eyes between rounds 12 and 13, approximately 10 to 12 stitches apart. This is also a good time to begin stuffing the body firmly with fiberfill.

Rnd 19: [Sc 3, dec] x 6. (24 sts)
Rnd 20: [Sc 2, dec] x 6. (18 sts)
Rnd 21: [Sc 1, dec] x 6. (12 sts)
Rnd 22: Dec x 6. (6 sts)

Finish stuffing the body fully, then close the opening by weaving the yarn tail through the front loops of the remaining 6 stitches and pulling tight. Weave in the end and set the body aside.

Part Two: The Bill

The bill is what makes this amigurumi instantly recognizable as a platypus. It should be flat and wide, like a slightly rounded paddle. Use your beige or cream colored yarn for this piece.

Ch 10.

Rnd 1: Starting in the second ch from the hook, sc 8, then sc 3 in the last ch (you’re turning the corner to work along the other side of the chain). Sc 7 along the other side, then sc 2 in the first ch you started in. (20 sts) Place a stitch marker to mark the beginning of the round.
Rnd 2: Inc, sc 7, inc 3, sc 7, inc 2. (26 sts)
Rnd 3: Sc 1, inc, sc 7, [sc 1, inc] x 3, sc 7, [sc 1, inc] x 2. (32 sts)
Rnd 4: Sc around in each st. (32 sts)

Slip stitch to close and leave a long tail for sewing. The bill does not need to be stuffed; it should remain flat and slightly floppy, which is very true to the real animal. Lightly stuff just the front half if you’d like a tiny bit of dimension, but keep it minimal.

Part Three: The Tail

The platypus’s tail is broad and flat, similar to a beaver’s, but proportionally smaller on the body. Use your main brown yarn.

Ch 8.

Rnd 1: Starting in the second ch from hook, sc 6, sc 3 in the last ch, sc 5 along the other side, sc 2 in the first ch. (16 sts)
Rnd 2: Inc, sc 5, inc 3, sc 5, inc 2. (22 sts)
Rnd 3: Sc 1, inc, sc 5, [sc 1, inc] x 3, sc 5, [sc 1, inc] x 2. (28 sts)
Rnd 4: Sc around. (28 sts)
Rnd 5: Sc around. (28 sts)

Slip stitch to close and leave a long tail for sewing. Like the bill, the tail should remain fairly flat. You can sew both layers together with a couple of stitches through the middle to keep it from puffing up if needed.

Part Four: The Legs (Make Four)

Platypus legs are short and wide, with webbed feet that splay out slightly. Make all four the same way.

Use main brown yarn.

Rnd 1: MR, 6 sc. (6 sts)
Rnd 2: Inc in each st. (12 sts)
Rnd 3: [Sc 2, inc] x 4. (16 sts)
Rnd 4: Working in BLO, sc around. (16 sts) — this creates a slight ridge that defines the foot.
Rnds 5–7: Sc around in each st. (16 sts)
Rnd 8: [Sc 2, dec] x 4. (12 sts)

Stuff lightly — the legs should be firm but not hard. Close to 6 sts and leave a long tail. You do not need to fully close these; you can leave a small opening and flatten the top of the leg before sewing it to the body. Flattening them gives the legs that characteristic wide platypus stance.

Part Five: The Ears (Make Two)

Platypus ears are very small and subtle — more like slight ridges on the sides of the head. These are simple oval pieces worked in the round.

Use main brown yarn.

Rnd 1: MR, 6 sc. (6 sts)
Rnd 2: [Sc 1, inc] x 3. (9 sts)
Rnd 3: Sc around. (9 sts)

Slip stitch and leave a long tail. Do not stuff. These will be sewn flat against the sides of the head.

Part Six: The Underbelly Panel (Optional but Recommended)

For a beautiful realistic touch, you can add a small cream or beige oval panel to the front of the body to represent the platypus’s lighter underbelly. This piece gets sewn directly onto the front of the body before you attach the other parts.

Use cream or beige yarn.

Ch 5.

Rnd 1: Starting in the second ch from hook, sc 3, sc 3 in the last ch, sc 2 along the other side, sc 2 in the first ch. (10 sts)
Rnd 2: Inc, sc 3, inc 3, sc 3, inc 2. (16 sts)
Rnd 3: Sc 1, inc, sc 3, [sc 1, inc] x 3, sc 3, [sc 1, inc] x 2. (22 sts)
Rnds 4–5: Sc around. (22 sts)

Fasten off and leave a long tail. Using your yarn needle, sew this oval flat against the front of the body using whip stitch or mattress stitch around the edge. Keep the stitches small and even so the seam is as invisible as possible.

Assembling Your Platypus

Now comes the most satisfying part: putting your platypus together. Lay all your finished pieces out on a flat surface before you begin sewing anything. Arranging them first lets you find the placement you like best.

Attaching the bill: Center the bill on the front of the body, positioning it at approximately rounds 8 through 12 (roughly where the face is). The bill should protrude forward and hang slightly downward. Sew around the back edge of the bill to attach it to the face, leaving the front and sides free so it remains floppy and three-dimensional.

Attaching the ears: Sew the ears flat against the sides of the head, about two rounds above where the eyes are inserted. They should sit close to the eyes, following the natural curve of the head.

Attaching the legs: Position the two front legs on either side of the body at roughly rounds 17 to 18 (near the lower front of the body). The back legs go at the very base of the body, just ahead of where the tail will attach, at rounds 20 to 21. Sew them in place so that when the platypus sits, all four legs splay out naturally to the sides.

Attaching the tail: Sew the tail to the back center of the body at the very base, aligning it horizontally so it extends straight out behind the figure. A few firm stitches on each side will hold it securely.

Attaching the underbelly: If you crocheted the underbelly panel separately, it should already be sewn on from the previous step. If you want to add it now, position it on the front of the body so it sits between the front and back legs, centered and slightly toward the bottom.

Once all pieces are attached, weave in any remaining yarn tails and give your platypus a gentle squeeze to make sure everything is firmly stuffed and well-shaped. Adjust any pieces that have shifted and re-sew if needed.

Finishing Touches

If you didn’t use safety eyes and want to embroider the eyes instead, thread a length of black yarn onto your needle and make several small satin stitches layered on top of each other to form solid, round eyes. A tiny white highlight stitch offset slightly to one side will make the eyes look bright and alive.

You can also use a small piece of black yarn to embroider a subtle nostril on each side of the bill if you want a little extra detail.

For a truly polished finish, give your finished platypus a very light steam using a garment steamer held several inches away from the surface. This relaxes the yarn fibers and evens out any slightly uneven stitches without distorting the shape. Never place an iron directly on amigurumi.

Tips for Success

One of the most common challenges in amigurumi is keeping your tension even throughout the project. If you find your stitches are too loose and the stuffing shows through, try going down half a hook size or consciously tightening your tension as you work.

When sewing pieces together, always use the same yarn you used to crochet each piece. This makes the seams blend in naturally. If you’re working with a fuzzy or textured yarn that’s difficult to thread through a needle, use a smooth tapestry thread in a matching color for the seaming instead.

Keep your magic rings tight. A loose magic ring will leave a visible hole at the top of your pieces, which is especially noticeable on the ends of the legs and ears.

If your bill or tail wants to curl up rather than lying flat, try blocking it. Dampen the piece lightly with water, shape it flat, and pin it to a foam blocking mat or a folded towel until it dries completely.

Yarn Substitutions and Color Variations

The traditional platypus is a rich brown with a pale underside, but your amigurumi can be any color you like. Soft teal or periwinkle gives the platypus a whimsical storybook quality. A pastel lavender version would make a beautiful baby shower gift. You could even go for a realistic dark chocolate brown with a warm tan belly for a more naturalistic look.

If you want to reduce the number of yarn colors you’re working with, skip the underbelly panel entirely. The platypus will still look completely charming with a single solid color all over.

Ideas for Displaying and Gifting Your Platypus

Amigurumi platypuses make wonderful gifts for nature lovers, biology enthusiasts, and anyone who appreciates the wonderfully weird side of the animal kingdom. They’re a conversation piece on a bookshelf, a soft companion for a stuffed animal collection, or a quirky desk ornament.

If you’re making one as a gift for a child, always use embroidered
