Oh My! Attack of the Octopi! – Knitted Octopus Pattern

There is something deeply irresistible about a knitted octopus. Maybe it is those eight dangling legs, each one begging to be curled around a finger or tucked under a child’s chin at bedtime. Maybe it is the way a simple sphere of yarn can be transformed into something so full of personality that people stop and stare in craft fairs, yarn shops, and across the internet. Whatever the reason, knitted octopus patterns have taken the fiber arts world by storm, and once you make your first one, you will absolutely understand why.

This pattern is affectionately called “Oh My! Attack of the Octopi!” because one is never enough. You will finish your first little cephalopod and immediately cast on another in a different color. Then another. Before long your sofa will be overrun, your yarn basket will be suspiciously lighter, and your family members will each have a personalized octopus sitting on their nightstand. Consider yourself warned.

Whether you are a beginner knitter looking for a satisfying first amigurumi-style project or an experienced crafter searching for the perfect handmade gift, this pattern delivers. It is compact, customizable, endlessly charming, and — best of all — it uses up scraps of yarn you probably already have sitting around. Let’s dive in.

Why Knit an Octopus?

Before we get to the needles and yarn, it is worth taking a moment to appreciate just how perfect the octopus is as a knitting subject. Unlike some creatures that require careful shaping of beaks, snouts, wings, or ears, the octopus has a beautifully simple silhouette — a rounded head and eight tentacles. That simplicity makes it approachable for newer knitters while still offering plenty of room for embellishment and creativity for those who want to push further.

Knitted octopus toys have also gained recognition in neonatal care communities. Premature babies are often soothed by the tentacles of a soft octopus toy, which can mimic the feeling of the umbilical cord and help calm them. Many hospitals have octopus knitting programs where volunteers donate handmade octopus toys to neonatal intensive care units. If you are looking for a reason to knit beyond personal enjoyment, this is one of the most meaningful ones you will ever find.

Beyond that practical element, knitted octopuses make extraordinary gifts. They are cheerful, whimsical, and universally loved across age groups. Toddlers adore them. Teenagers think they are cool. Adults display them on their desks at work. If you knit gifts for people in your life, adding an octopus to your repertoire is one of the best decisions you can make.

Materials You Will Need

One of the greatest joys of this pattern is how little you need to get started. Here is what you will want to gather before you cast on.

Yarn: Worsted weight yarn works beautifully for this pattern and creates a toy that is sturdy enough to handle enthusiastic play. You can absolutely use DK weight for a smaller finished octopus or bulky yarn for an oversized statement piece. Almost any fiber works — acrylic is practical and machine washable, making it ideal for children’s toys, while cotton gives a lovely firmness and is also washable. If you are knitting for a newborn or a child with sensitivities, look for soft, hypoallergenic options. You will need roughly 50 to 100 yards of your main color depending on the finished size you want.

Needles: A set of double-pointed needles in the size recommended for your yarn works best, since this pattern is knitted in the round. A short circular needle (16 inches) works well for the body, though you may find it easier to use double-pointed needles throughout, especially as you decrease at the top of the head. A needle size that gives you a slightly tighter gauge than the yarn label recommends will help prevent the stuffing from showing through.

Stuffing: Polyester fiberfill is the standard choice and gives a nice, plush finish. For toys intended for very young children, use stuffing certified as safe for babies. If you want a bit of weight to your octopus — which makes it feel more satisfying to hold — you can mix in a few pellets or even a small amount of rice wrapped in a fabric pouch inside the stuffing.

Eyes: Safety eyes are the popular choice for toys and give the octopus an immediately expressive, finished look. If you are knitting for a child under three, safety eyes are not recommended due to choking risk — embroidered eyes using satin stitch or French knots are a much safer alternative and can look absolutely adorable.

Tapestry needle and scissors: You will need these for finishing, sewing, and weaving in ends.

Optional: Stitch markers, a row counter, and a small amount of contrasting yarn for embroidered details.

Gauge and Sizing

For a standard-sized toy octopus using worsted weight yarn on US size 5 or 6 needles, you can expect a finished body diameter of approximately 4 to 5 inches and tentacles around 3 to 4 inches long. The finished height from the top of the head to the tips of the tentacles will be roughly 7 to 8 inches.

Gauge is not critical for this pattern in the way it is for a fitted garment, but you do want your knitting to be tight enough that the stuffing does not poke through. If you can see light through your knitted fabric when you hold it up, go down a needle size.

Part One: The Head

The head is worked from the top down in the round. This approach means you can close the top neatly and work your way down toward the tentacles, stuffing as you go.

Cast on 6 stitches. Distribute evenly across three double-pointed needles (2 stitches per needle) and join to work in the round, being careful not to twist.

Round 1: Kfb in every stitch. (12 stitches)

Round 2: Knit all stitches.

Round 3: K1, Kfb; repeat from to end. (18 stitches)

Round 4: Knit all stitches.

Round 5: K2, Kfb; repeat from to end. (24 stitches)

Round 6: Knit all stitches.

Round 7: K3, Kfb; repeat from to end. (30 stitches)

Round 8: Knit all stitches.

Round 9: K4, Kfb; repeat from to end. (36 stitches)

Rounds 10–20: Knit all stitches for 11 rounds.

This creates a nice dome-shaped head. If you want a larger octopus, you can continue increasing in this pattern (adding one more stitch between increases each time) and then knit additional straight rounds.

Now it is time to add the safety eyes. Place them between rows 12 and 14, roughly 8 to 10 stitches apart. Attach them firmly before closing the head.

Round 21: K4, K2tog; repeat from to end. (30 stitches)

Round 22: Knit all stitches.

Round 23: K3, K2tog; repeat from to end. (24 stitches)

At this point, begin stuffing the head. Add a generous amount of fiberfill — you want it to be firm and well-rounded. Continue stuffing as you work the remaining decrease rounds.

Round 24: K2, K2tog; repeat from to end. (18 stitches)

Round 25: K1, K2tog; repeat from to end. (12 stitches)

Round 26: K2tog around. (6 stitches)

Cut yarn, leaving a 6-inch tail. Thread tail onto tapestry needle and draw through remaining 6 stitches. Pull tight and fasten off. Weave in end securely.

Part Two: The Tentacles

Eight tentacles, each one a little tube of delight. You can knit them all in the same color as the body, or mix and match for a festival of color. Each tentacle is knitted separately and then attached to the bottom of the head.

For each tentacle:

CO 8 stitches onto dpns. Join to work in the round.

Rounds 1–20: Knit all stitches.

At this point you have a plain tube. For added texture and that wonderful curly tentacle look, you have two options.

Option A (Simple): BO all stitches and leave the tentacle un-stuffed. The tube will naturally curl slightly. Sew the cast-on end to the bottom of the head.

Option B (Curly tentacles): On your bind-off row, Kfb in every stitch before binding off. This creates extra fabric that causes the tentacle to curl dramatically. It is a little more fiddly but the result is very satisfying and looks wonderfully octopus-like.

Option C (Tapered tentacles): For a more realistic look, work a few decreases toward the end of the tentacle. On round 16, work K2tog at the beginning of the round, then knit to end. Repeat this decrease on rounds 18 and 20. BO remaining stitches. This gives a gentle taper to each tentacle.

Make eight tentacles. If they feel a little floppy, you can stuff each one loosely with a small amount of fiberfill before sewing them on.

Part Three: Assembly

This is the part where your octopus comes to life.

Lay the eight tentacles out evenly around the bottom of the head. Space them as evenly as possible — four in a row across the front, four across the back works well, or you can arrange them in a circle. Think of it like a clock: tentacles at 12, 1:30, 3, 4:30, 6, 7:30, 9, and 10:30.

Using your tapestry needle and a length of matching yarn, sew each tentacle firmly to the base of the head. The seam should be neat and secure — these tentacles will be tugged, so take your time here. Work in a circle, attaching all eight tentacles, then go around again to reinforce.

Part Four: The Face

The face is where your octopus gets its personality. If you placed safety eyes already, great — that is the bulk of the expression taken care of. Now you can embroider a little smile or smirk using a couple of stitches of dark yarn. A simple horizontal line with a slight curve at each end is all it takes to go from blank to beaming.

You can also embroider little suckers on the tentacles using French knots in a contrasting color. This is completely optional but adds a wonderful handcrafted touch.

Color Ideas and Variations

One of the most exciting things about this pattern is how dramatically different it looks depending on your yarn choices. Here are some color ideas to get your imagination going.

A deep indigo blue with silver eyes makes a mystical, deep-sea octopus that looks like it belongs in a fantasy novel. Bright orange with googly safety eyes is cheerful and playful. A speckled or variegated yarn in ocean tones creates a gorgeous naturalistic effect without any extra effort. Soft lavender or mint green makes a sweet toy for a nursery. If you are feeling ambitious, you can knit each tentacle in a different color for a rainbow octopus that will absolutely steal every show it walks into.

You can also add embellishments like a tiny knitted bow attached between the eyes, or a small hat made from a scrap of yarn. Some knitters add a ruffled collar around the base of the head where it meets the tentacles, which gives the octopus an air of Victorian elegance.

Tips for Success

Keep your tension consistent throughout. If your tension loosens up as you get tired or distracted, your octopus will have an uneven, lumpy head. Taking a break and coming back fresh often makes a noticeable difference.

Use a stitch marker at the beginning of each round so you always know where you are. It sounds simple but it will save you from having to count back through rows when you lose track.

When stuffing the head, resist the urge to under-stuff. A well-stuffed octopus head keeps its round shape much better over time. However, avoid over-stuffing to the point where the knitted fabric stretches and the stuffing shows through.

When sewing on the tentacles, use the same yarn you knitted with whenever possible. A contrasting color thread or yarn will show at the attachment point and can look messy.

If you are planning to wash the finished octopus, check the care instructions on your yarn label. Most acrylic and cotton toys can be machine washed on a gentle cycle in a mesh laundry bag. Wool and wool-blend octopuses should be hand washed in cool water.

Gifting Your Octopus

A handmade octopus toy is one of the most thoughtful and personal gifts you can give. For a new baby, choose soft, washable yarn in gentle tones and embroider the eyes rather than using safety eyes. For a child who loves the ocean, use ocean-inspired colors and consider adding a little tag that explains some fun octopus facts — did you know that octopuses have three hearts and blue blood? Children go absolutely wild for that kind of detail.

For an adult friend, consider a desk octopus in their favorite color with a little embroidered expression that matches their personality. You can give a grumpy octopus to the friend who hates Mondays, an enthusiastic wide-eyed octopus to the friend who is always excited about everything, or a dignified octopus with a tiny bow tie to the colleague who takes themselves a bit too seriously.

Pair the octopus with a skein of yarn, a handwritten card explaining the pattern so they can make their own, or a little ocean-themed book for a gift basket that feels truly curated and personal.

Joining the Octopus Knitting Community

If you make one of these little octopuses, share it. Post a photo using the hashtag #AttackOfTheOctopi and tag your yarn of choice. The knitting community online is warm, enthusiastic, and absolutely delighted by a good octopus photo. Ravelry is a wonderful resource for connecting with other knitters, finding yarn substitutions, and even finding local knitting groups.

If you are interested in donating octopus toys to neonatal care units, search online for your nearest hospital program or charity that facilitates this — there are organizations around the world that coordinate donations of knitted octopus toys and can guide you on specific requirements for size, materials, and construction.

Final Thoughts

The “Oh My! Attack of the Octopi!” knitted octopus pattern is exactly what it promises: a delightful, fast, satisfying knit that produces something genuinely wonderful at the end. Whether you make one or twenty — and if you are anything like most knitters who discover this pattern, it will be closer to twenty — each finished octopus carries a little piece of handmade charm that no store-bought toy can replicate.

Pick up your needles, choose your favorite yarn, and let the attack begin.
