Cute Crochet Jellyfish Pattern (Free Amigurumi)

Jellyfish plushies have quietly become one of the most-made amigurumi shapes on crochet feeds, and it is easy to see why. The whole animal is really just two simple pieces – a soft stuffed dome for the head, and a handful of curly tentacles that spiral all on their own thanks to a clever bit of stitch math, not any special skill. If you can single crochet in a spiral round and chain a length of stitches, you already have every skill this pattern asks of you.

This is a true beginner amigurumi pattern. Every round below comes with its own stitch count, so you always know whether you are on track, and the dreamy curl in the tentacles happens automatically once you pack extra stitches into a shorter chain. Pick a pastel or iridescent worsted weight yarn and let’s make something soft enough to squeeze all day.

What You Will Need

– About 100 yards of worsted weight (#4) yarn in your main color, plus small amounts of one or two accent colors for the tentacles if you want an ombre look – A 4.0mm crochet hook – Polyester fiberfill stuffing – A yarn needle, for weaving in ends and closing the final gathers – A removable stitch marker, to track the start of each round – Scissors – Optional: small safety eyes or embroidery floss, for a simple face

Abbreviations

MR = magic ring; ch = chain; sc = single crochet; inc = increase (work 2 sc into the same stitch); dec = decrease (single crochet the next 2 stitches together); st(s) = stitch(es); rnd = round; sl st = slip stitch

The Head

Work in continuous spiral rounds (do not join or turn) unless a step says otherwise. Move your stitch marker up into the last stitch of each round as you finish it.

– Rnd 1: MR, work 6 sc into the ring, pull the tail to close. (6 sc) – Rnd 2: Inc in each st around. (12 sc) – Rnd 3: *Sc 1, inc in next st; rep from * around. (18 sc) – Rnd 4: *Sc 2, inc in next st; rep from * around. (24 sc) – Rnds 5-10 (6 rounds): Sc in each st around, no increases. (24 sc each round) – Rnd 11: *Sc 2, dec next 2 sts; rep from * around. (18 sc) – Rnd 12: *Sc 1, dec next 2 sts; rep from * around. (12 sc)

Stuff the head firmly now, before the opening gets too small to reach into. A jellyfish plushie looks best nice and full, so pack in a little more fiberfill than feels necessary.

Closing the bottom edge: Fasten off, leaving a 12-inch tail. Thread the tail onto your yarn needle and weave it through the front loop of each of the 12 remaining stitches around the opening. Pull gently to gather it mostly closed, but stop before it lies completely flat – you will use these same 12 loops as anchor points for the tentacles in the next step, so leave enough of a gathered edge that you can still see and count each stitch.

The Tentacles

Make 6 tentacles. Each one is worked flat, then curls into a spiral entirely on its own.

For each tentacle: Chain 21. Starting in the 2nd chain from your hook, work 3 sc in each chain across (20 chains x 3 sc = 60 sc total). Fasten off, leaving a few inches of tail at both ends.

Because you are packing three stitches onto a base that only has room for one, the strip cannot lie flat – it spirals into a tight, dreamy curl without any special shaping. Make all 6 tentacles the same way before you move on to assembly.

Putting It Together

1. Lay the head bottom-up and find the 12 gathered loops you left in the closing step. 2. Space the 6 tentacles evenly around the edge, attaching one tentacle to every other loop (12 sts divided by 6 tentacles = 2 sts between each attachment point). Use the tentacle’s starting tail to stitch it in place through the gathered loop, then run the tail through to the inside and trim. 3. Once all 6 tentacles are attached, pull the head’s original closing tail the rest of the way snug, secure it with a couple of small stitches, and weave in the end. 4. Weave in every remaining tail, including the loose ones at the bottom tip of each tentacle. 5. Add a simple face if you like – two small safety eyes or a couple of embroidered stitches sit nicely just above the halfway point of the dome.

That is genuinely the whole plushie: one stuffed dome and six curly tentacles.

Tips for a Dreamier Jellyfish

– Do not skip the stitch marker. Twelve rounds of spiral single crochet with no natural “end” is exactly how beginners lose their place – a moved-up marker keeps you honest. – Recount after every increase or decrease round. If your total does not match the count listed above, it is far easier to fix on the round you just made than three rounds later. – Vary the tentacle length for a livelier look. A chain anywhere from 18 to 24 still curls beautifully, and a mix of lengths reads as more natural movement than six identical strands. – Iridescent or self-striping yarn is a shortcut to “dreamy.” Since there is no shaping to interrupt a color change, this is a forgiving project to test a special skein on.

Quick FAQ

Why is my tentacle not curling as tightly as expected? Tension is usually the cause. A looser chain and a looser sc will curl less dramatically, so try working both slightly tighter than your usual gauge.

Can I use a different yarn weight? Yes. A lighter DK weight with a smaller hook makes a daintier plushie, while chunky yarn and a larger hook makes a bigger, huggable version – just expect the yardage and finished size to shift with it.

Do I have to use exactly 6 tentacles? No. Real jellyfish have far more, so anywhere from 6 to 10 still reads correctly. Just keep the spacing even around your 12 anchor loops – a count like 4, 6, or 12 tentacles divides evenly, while other counts will land slightly lopsided.

Once the last tail is woven in, you have a squishy, dreamy little jellyfish that took nothing more exotic than single crochet, a chain, and a bit of stuffing. Set it on a shelf, clip it to a bag, or make a whole bloom of them in every pastel you own.

Frequently asked questions

How firmly should I stuff the head before closing the last rounds?

Pack it more than feels necessary. The pattern calls for firm stuffing at Rnd 12 specifically because a full, rounded dome is what makes a jellyfish plushie look right, rather than a soft, collapsed shape.

Do the tentacles need to be sewn on, or can they be crocheted directly into the gathered edge?

Sewing them on with the tentacle’s own starting tail through the gathered front loops is simpler for a first jellyfish than trying to join a new piece with a slip stitch into a spot that’s already partly closed.

My dome looks lopsided after the decrease rounds. What went wrong?

It’s almost always a missed increase or decrease earlier in the round rather than a problem with the decreases themselves. Recount Rnd 4, which should have 24 sc, since that’s the widest point and any error there carries through every later round.

How do I stop all six tentacles from tangling while I attach them?

Lay them out flat around the head in the order you plan to sew them before you start, then attach them one at a time working around the circle in one direction rather than jumping back and forth.

Can I make flatter, ribbon-like tentacles instead of tightly curled ones?

Yes, working fewer stitches per chain, such as 2 sc per chain instead of 3, reduces the curl significantly and gives you a looser, wavier tentacle instead of a tight spiral.
