Pink Jellyfish Keychain Charm Crochet Pattern | Cute Amigurumi Bag Charm

If you’ve been searching for the most adorable little crochet project to add to your collection, this pink jellyfish keychain charm pattern is exactly what you need. Whether you’re a beginner looking for a quick and satisfying make or an experienced crocheter who loves tiny amigurumi, this pattern walks you through creating the cutest ocean-inspired bag charm you’ll ever hang from your tote. Soft, squishy, and impossibly sweet, this little jellyfish takes only a small amount of yarn and a couple of hours to complete — making it the perfect weekend project, gift idea, or stash-buster.

Let’s dive in (pun absolutely intended).

Why You’ll Love This Pattern

Jellyfish are having a major moment in the crafting world, and it’s easy to see why. Their rounded bell shape and flowing tentacles translate beautifully into amigurumi, and the finished piece looks like it came straight from a boutique shop. The pink colorway makes this particular charm feel playful and sweet — perfect for spring and summer, but charming enough to carry year-round.

What makes this pattern especially fun is how versatile the finished charm is. You can attach it to a keychain ring and clip it to your keys, hang it from a tote bag zipper, dangle it from a backpack, or even use it as a gift topper. It also works beautifully as a plushie ornament or a handmade gift tag. Small but mighty, this little jellyfish carries a lot of personality for its size.

The pattern uses basic amigurumi techniques — magic ring, single crochet, increases, decreases, and a few simple chain stitches for the tentacles — so even if you’re fairly new to crochet, you’ll be able to follow along without feeling overwhelmed.

Materials You’ll Need

Before you start crocheting, gather your materials. Because this is a small project, you won’t need large quantities of anything, which makes it a great stash buster.

Yarn: A small amount of pink worsted weight yarn for the body. You can use any shade of pink you love — soft blush, bubblegum pink, hot pink, or a variegated yarn with pink tones all work wonderfully. You’ll also want a tiny bit of white or light pink yarn for any accent details if you choose to add them. Approximately 15–20 grams of yarn is more than enough to complete one jellyfish.

Hook: A 2.5mm or 3mm crochet hook is ideal for amigurumi to keep the stuffing hidden and give the fabric a tight, clean look. Adjust based on your tension and the yarn weight you’re working with.

Stuffing: A small amount of polyester fiberfill stuffing. You only need enough to fill the rounded bell of the jellyfish — a small pinch goes a long way.

Safety Eyes: Two 6mm black safety eyes. If you’re making this for a child under three, skip the safety eyes and embroider the eyes instead using black yarn or embroidery floss.

Keychain Ring or Lobster Clasp: A metal keychain ring, split ring, or lobster clasp to attach the finished charm. You can find these at any craft store or online in bulk packs.

Tapestry Needle: For weaving in ends and sewing pieces together if needed.

Scissors

Stitch Markers: Optional but helpful for marking the beginning of each round.

Gauge and Finished Size

Gauge isn’t critical for amigurumi, but using a smaller hook than your yarn typically calls for will create a tighter fabric that holds its shape and conceals the stuffing better. With a 3mm hook and worsted weight yarn, the finished jellyfish body measures approximately 5–6 cm (about 2–2.5 inches) across at its widest point. The tentacles hang down approximately 4–6 cm below the body, depending on how long you make them. The total finished charm, including the chain loop at the top for attaching the keychain ring, measures roughly 10–12 cm (about 4–5 inches) from top to bottom.

Pattern: Pink Jellyfish Body

The jellyfish body is worked in continuous rounds. Use a stitch marker to mark the first stitch of each round so you don’t lose your place.

Round 1: Start with a magic ring. Work 6 SC into the ring. Pull the tail to close the ring. (6 stitches)

Round 2: INC in each stitch around. (12 stitches)

Round 3: SC 1, INC repeat around. (18 stitches)

Round 4: SC 2, INC repeat around. (24 stitches)

Round 5: SC 3, INC repeat around. (30 stitches)

Round 6: SC 4, INC repeat around. (36 stitches)

Round 7–10: SC in each stitch around. (36 stitches per round — 4 rounds total)

At this point, insert your safety eyes between Rounds 5 and 6, approximately 6–8 stitches apart. This is the front of the jellyfish. If you’d like to embroider a smile, do so now using black yarn or embroidery floss before you begin closing up the body. A small curved stitch just below the eyes creates the sweetest little expression.

Round 11: SC 4, SC2TOG repeat around. (30 stitches)

Round 12: SC 3, SC2TOG repeat around. (24 stitches)

Begin stuffing the body now. Add fiberfill gradually, being careful not to overstuff. The body should feel firm but not stretched. A lightly stuffed, rounded bell shape is what you’re going for.

Round 13: SC 2, SC2TOG repeat around. (18 stitches)

Round 14: SC 1, SC2TOG repeat around. (12 stitches)

Round 15: SC2TOG around. (6 stitches)

Add a final small pinch of stuffing if needed, then close the opening. You can either use your tapestry needle to weave the yarn through the remaining 6 stitches and pull tight to close, or continue with SC2TOG until you have just 3 stitches left and pull tight. Fasten off and weave in the end.

Pattern: The Tentacles

The tentacles are what really bring this jellyfish to life. You’ll make six tentacles in total — three shorter ones framing the body and three longer, more dramatic ones hanging down from the center underside. This combination of lengths gives the jellyfish a natural, flowing look.

Work the tentacles directly onto the bottom edge of the jellyfish body by joining your yarn at the underside opening (the last round you closed up).

Three Long Tentacles:

Join your yarn at the bottom center of the jellyfish. Chain 20. In the second chain from the hook, SC all the way back up the chain. Slip stitch into the body to secure. Fasten off and weave in end. Repeat for the two other long tentacles, spacing them evenly.

Three Short Tentacles:

Join your yarn slightly outward from the long tentacles. Chain 12. In the second chain from the hook, SC all the way back up the chain. Slip stitch into the body to secure. Fasten off and weave in end. Repeat for the remaining two short tentacles.

The single crochet worked back along the chain creates a natural curl and texture in each tentacle, mimicking the way real jellyfish tentacles move in the water. If you’d like even more curl, use a smaller hook for the tentacles than you used for the body.

Feel free to customize the tentacle count and length. Some crocheters prefer eight tentacles of varying lengths, others like a full fringe of twelve shorter ones for a fluffy, sea-anemone look. This is your jellyfish — make it your own.

Finishing: Adding the Keychain Loop

To turn your jellyfish into a proper keychain charm or bag charm, you’ll need to add a loop or small hanging point at the top of the body.

Thread your tapestry needle with a length of pink yarn approximately 20 cm long. Push the needle down through the top center of the jellyfish (the point where you started your magic ring) and bring it back up about 2–3 stitches away. Pull both yarn ends so they’re even and tie them together in a secure knot, forming a small loop at the top of the jellyfish. Trim and weave in the ends carefully.

Alternatively, you can crochet a small chain loop: join yarn at the top of the jellyfish, chain 8–10, slip stitch back into the starting point to form a ring, and fasten off. This creates a neat loop that looks tidy and holds up well to daily use.

Thread your keychain ring or lobster clasp through the loop and close it securely. Your charm is ready to use.

Customization Ideas

One of the best things about small amigurumi projects like this one is how easy they are to personalize. Here are some ideas to make your pink jellyfish keychain charm uniquely yours.

Color Variations: While pink is the star of this pattern, jellyfish look stunning in almost any color. Try lavender and white for a dreamy, ethereal look. Deep teal for an ocean vibe. Peach or coral for a tropical feel. A sparkly or metallic yarn adds an extra-special touch that looks gorgeous on bag charms.

Facial Expressions: Instead of a simple smile, you could add rosy cheeks using a small circle of pink felt or a few stitches of dusty rose yarn. Tiny blush circles on each side of the face make amigurumi look especially kawaii and sweet.

Sparkle and Texture: Using a fuzzy yarn, mohair, or a yarn with a subtle shimmer for the tentacles gives the finished piece a magical, otherworldly quality. You could also use a different yarn weight for the tentacles to create contrast in texture.

Size Scaling: If you want a larger jellyfish plushie rather than a keychain charm, simply scale up your yarn weight and hook size. Use chunky yarn with a 5mm or 6mm hook and you’ll have a palm-sized plushie in no time. The same pattern works at any scale — just adjust your materials accordingly.

Multiple Charms: These little jellyfish are so quick to make that many crocheters end up making a whole ocean’s worth. They make beautiful gifts, party favors, stocking stuffers, and craft fair items. A set of three in coordinating pink tones — blush, hot pink, and rose — looks stunning bundled together with a ribbon.

Tips for Perfect Amigurumi

If you’re newer to amigurumi, a few tips will help your finished jellyfish look polished and professional.

Always crochet tightly. The number one tip for amigurumi is to use a hook one or two sizes smaller than what your yarn label recommends. This creates a tighter fabric with no gaps for the stuffing to peek through.

Don’t overstuff. It’s tempting to really pack the fiberfill in, but overstuffing distorts the shape and puts unnecessary strain on the seams. You want just enough stuffing to give the body shape and a soft squish when pressed.

Weave in your ends thoroughly. Small amigurumi items get handled a lot, especially when they’re keychain charms. Take the time to weave in each end multiple times in different directions to keep everything secure.

Use a stitch marker consistently. Amigurumi is worked in continuous rounds, which means there’s no visible seam marking where one round ends and the next begins. A simple loop of contrasting yarn used as a stitch marker makes it much easier to keep track of your rounds.

Block if needed. If your tentacles are curling more than you’d like, a quick steam or wet blocking can help them relax into a more even shape. Lay them flat while damp and let them dry completely.

Skill Level and Time Estimate

This pattern is suitable for beginners to intermediate crocheters. If you know how to crochet a magic ring, single crochet, increase, and decrease, you have all the skills you need. The tentacles involve no special stitches — just chains and single crochets — so even complete beginners can tackle this one.

Most crocheters finish a single jellyfish in one to three hours depending on experience level. It’s a wonderful project to work on during a movie, a commute, or a quiet evening at home. Once you’ve made one, you’ll find you can make the second and third considerably faster as your hands learn the rhythm.

How to Use Your Finished Charm

The finished pink jellyfish amigurumi charm is as versatile as it is cute. Here are some of the many ways to use and gift it.

Clip it to your everyday tote bag for a pop of handmade charm. Add it to a backpack zipper pull for a fun and personal touch. Attach it to your keys so you can find them easily while adding a little joy to your day. Hang it from a lanyard, a pencil case, or a planner charm ring. Use it as a gift topper on a birthday or baby shower present — it doubles as a keep-forever keepsake. Add a ribbon and hang it from a Christmas tree for a sweet ocean-themed ornament. Include it in a care package or swap package for a crocheter friend.

Sharing Your Makes

If you make this pink jellyfish keychain charm, we’d absolutely love to see it. Share your finished charm on Instagram, Pinterest, or your favorite crafting community and tag it so other crocheters can find and admire your work. The crafting community thrives on shared inspiration, and your version of this pattern might be exactly the motivation someone else needs to pick up their hook for the first time.

Crochet is one of the most wonderfully portable crafts, and small amigurumi projects like this one are proof that you don’t need a lot of time, money, or space to make something truly beautiful. A bit of pink yarn, a small hook, and an hour or two is all it takes to create a tiny piece of ocean magic you’ll carry with you everywhere.

Happy crocheting, and may your tentacles always curl perfectly.
