All of these can learnt in less than 30 minutes. You can also crochet them as you go. I have already shared fish keychain patterns, so be sure to check them, too. And soon, I will also extend this series to include many more unique ideas for all skill levels. Let’s get started for now!
01 of 05 Crochet Octopus Sea Creature Keychain
This tiny octopus is a brilliant “no-sew” project that makes a perfect quick-gift keychain. It features a round head with wavy tentacles worked directly into the piece for a seamless, sturdy finish.
General Making:
The making begins with a magic ring for the head, working down in single crochet rounds before creating the tentacles in the front loops only. Each tentacle is made by clustering different stitches into a single space to get that signature wavy edge. To finish, a small flat base is crocheted separately and joined to the main body’s back loops while stuffing, keeping the entire project needle-free.

02 of 05 Crochet Squid Sea Creature Handmade Toy Keychain
If you’ve got a lot of scrap yarn lying around, this little squid is the perfect way to clear it out. It’s a flat, stylized charm rather than a bulky stuffed toy, giving it a cool, modern look that’s great for summer bags or keychains. The wide, expressive eyes take up most of the body, which gives it a quirky personality that really stands out.
General Making:
To get that sharp triangular shape, you start with a magic circle and use strategic single crochet increases at three specific points. Once the body is finished, you jump right into the tentacles by chaining out from the bottom edge and working half-double crochets back up. The whole thing is finished off by crocheting two tiny white circles for the eyes and gluing them on, making it a super fast project with a lot of character.

03 of 05 Crochet Fish Sea Creature Keychain
This goldfish is a 3D amigurumi that uses vibrant yarn and simple shaping to create a body that’s sturdy enough to survive being tossed around in a bag. The standout feature is definitely the oversized tail fin, which gives the fish a sense of movement even though it’s just a small keychain.
General Making:
The making process starts with a magic ring for the nose, expanding into a round ball using standard single crochet increases. Once you’ve reached the desired size and stuffed the body, you flatten the tail end and work a series of double crochets and chains directly into the back to create the fanned-out fin. To finish it off, you add two side fins and secure a pair of safety eyes near the front to give it that wide-eyed, bubbly expression.

04 of 05 Crochet Seal Sea Creature Keychain
Soft chenille yarn makes this seal incredibly squishy and gives it a velvety, high-end feel. It has a smooth, tapered body that leads into a classic split tail, making it look like it’s ready to glide through the water. With its unique rectangular snout and tiny pink cheeks, it has a sweet, gentle expression that stands out from typical round plushies.
General Making:
To make it, start with a magic ring for the head and work in rounds, narrowing the shape as you reach the tail. The snout is crocheted separately with extra increases for an oval look and then sewn between the safety eyes. You’ll also need to make two flat flippers for the front and two leaf-shaped pieces that join at the back to form the tail, finishing with a little black embroidery for the nose.

05 of 05 Crochet Shrimp Keychain (BONUS)
Bright orange-pink yarn gives this shrimp a fun “cooked” look that makes it a perfect summer accessory. It’s a compact, portable keychain that captures all the quirky details, from the long whiskers down to the tiny legs.
General Making:
The process starts by crocheting a long, tapered tube that serves as the body. Once it’s stuffed, you use a strand of yarn to pull the tube into a curved arch, instantly giving it that signature shrimp shape. The whiskers and legs are just simple yarn strands stiffened with a little clear glue, and a few horizontal stitches along the back finish it off by mimicking a segmented shell.
