Gathering the right supplies first makes the whole project smoother and way more enjoyable.

• Yarn colors: Ocean blue or teal for the head, white or cream for the underside pattern, and soft coral or seafoam green for accent details
• Crochet hook: 2.5mm or 3.0mm hook (matched to worsted or DK weight yarn)
• Safety eyes: 8mm or 9mm black safety eyes, or small black beads for a mini version
• Stuffing: Polyester fiberfill, or yarn scraps for an eco-friendly option
• Needle and scissors: Yarn needle for sewing, sharp scissors for trimming yarn ends
• Keychain accessories: A metal keychain ring, a lobster clasp, or a lanyard clip
• Stitch markers: Small locking markers or scrap yarn loops to track your rounds

Crochet Techniques Used

Real talk, this pattern leans on a handful of core amigurumi techniques that any beginner can pick up quickly.

• Magic ring: Starts each piece with a tight, gap-free center
• Single crochet (sc): Builds the dense fabric amigurumi needs for stuffing
• Increase (inc): Two single crochets in one stitch to widen the shape
• Decrease (dec): Invisible decrease to narrow the shape smoothly
• Sewing parts together: Whip stitch or mattress stitch for a seamless finish

Step-by-Step Crochet Pattern Instructions

Head Creation

Start the head with a magic ring of 6 single crochets. Increase every stitch on round 2 to reach 12 stitches, then continue increasing every other stitch through round 4 until you hit around 24 stitches. Work several rounds even, without increasing, until the head reaches your desired roundness. Begin decreasing gradually near the top, leaving a small opening for stuffing.

Body Making

For this pattern, the head and body form one continuous rounded shape, so no separate body piece is needed. Keep the walls even by maintaining consistent tension throughout your rounds. Add stuffing gradually as you work, rather than cramming it all in at the end.

Tentacles and Accessories

Crochet eight tentacles separately using short chains or small rounds of single crochet, tapering each one slightly at the tip. For real, curling each tentacle slightly while sewing it on gives that classic wiggly octopus look. A tiny coral-colored shell or starfish appliqué makes a fun coastal accessory to attach near the head.

Facial Details

Place the safety eyes between rounds 8 and 10 of the head, spaced a few stitches apart for a friendly expression. Embroider a small curved mouth using pink or red yarn and a simple backstitch. A few pink cheek stitches add extra charm without much extra effort.

Assembly Process

Stuff the head firmly before closing the final round with a fasten-off and yarn needle. Attach all eight tentacles evenly around the bottom opening using a whip stitch, spacing them like a clock face for symmetry. Weave in every loose end carefully so nothing unravels with regular keychain use.

Finishing Touches

No joke, the keychain ring is what turns this cute amigurumi into a functional accessory. Sew a small loop of yarn or a metal jump ring securely into the top of the head, then clip on your keychain ring or lobster clasp. Give the whole piece a gentle shape and fluff before it’s ready to use.

Helpful Beginner Tips

• Keep stitches tight: Amigurumi needs a snug tension so stuffing never peeks through
• Use stitch markers: Mark the start of every round to avoid losing your place
• Stuff evenly: Add small amounts of stuffing gradually for a smooth, lump-free shape
• Count stitches often: Checking stitch counts after each round catches mistakes early

Design Customization Ideas

• Different colors: Try purple, pink, or sunset orange for a totally new coastal vibe
• Cute accessories: Add a tiny bow, a sailor hat, or a bead necklace
• Mini size variations: Work with a smaller hook and thinner yarn for a pocket-sized charm
• Personalized details: Embroider initials or use bead eyes instead of safety eyes for baby-safe gifts

Frequently Asked Questions

What is the best yarn for Crochet Octopus Keychain amigurumi?

Cotton or acrylic worsted weight yarn works best since both hold their shape well and hide stuffing effectively. Cotton gives a slightly firmer, more polished finish for keychains.

How do you make a crochet plush firm?

Firmness comes from tight stitches, a smaller hook size relative to your yarn, and steady, even stuffing throughout every part of the piece.

How long does this project take?

Most crocheters finish this octopus keychain in two to four hours, depending on experience level and how many tentacles get added.
