My Favorite Sea-Themed Amigurumi Patterns

There’s something irresistibly charming about crafting sea creatures with yarn and a hook. Sea-themed amigurumi bring a splash of ocean magic into your hands, whether you dream of beach escapes or love the colorful underwater world. Here, I’m sharing four of my all-time favorite ocean-inspired amigurumi patterns: crab, seagull, sea snail, and fish.

Crab (see cover image, pattern from Zoomigurumi Favourites)
Cute, quirky, and full of character, the crochet crab is a must-have in any sea-themed collection. With its round body, popping eyes, and lively pincers, a crab amigurumi is an instant mood-lifter. The construction is simple yet rewarding—perfect for both beginners and those seeking a quick, satisfying finish. I love using coral reds or bright oranges for that true-to-nature look. You can sew on a playful smile or fun little details, like freckles or a mini shell, to make your crab unique. These crabs are adorable as pocket pals, ocean playsets, or giveaways for summer parties.

Seagull  (pattern from Zoomigurumi Favourites)
Few things say “seaside” like the sight of a cheerful seagull. The crochet seagull amigurumi brings this iconic bird to life in soft yarn form, sporting a rounded body, long wings, a bright yellow beak, and tiny feet. One of the joys of this pattern is playing with color contrasts—the classic white body, grey wings, and yellow accents are easily recognizable. Finish off your seagull with embroidered eyes and maybe a little nautical scarf or sailor hat for extra character. Seagulls are perfect for beach-themed nurseries or as thoughtful gifts for ocean lovers.

Sea Snail (pattern from Lalylala's Beetles, Bugs And Butterflies by Lydia Tresselt)
Who would have thought a snail could be so cute? The sea snail amigurumi is gentle, whimsical, and full of charm. Its soft spiral shell and simple rounded body are great for practicing increases and color changes. You can use shiny or pastel shades to create a magical, underwater effect. Add tiny felt cheeks or safety eyes for a sweet, expressive face. Sea snails make fantastic companions for other marine creatures or as desk mascots—bringing a smile wherever they go.

Happy Fish (pattern by "Smoozy", www.smoozy-handmade.com)
Colorful, and endlessly customizable, the crochet fish amigurumi might be the most versatile sea-themed pattern of them all. With basic shapes, you can create everything from goldfish to clownfish or even fantasy mer-creatures by mixing unusual colors. The fins and tail are an opportunity for creative flair—try variegated yarns or embroidery for extra fun. Finished fish look wonderful in mobile decorations, as toys, or even as keychains.

Why I Love These Ocean Amigurumi
Each of these patterns has become a favorite because of their playfulness, creativity, and potential for personalization. Whether I’m making a crab with big, happy eyes or a shimmering fish, I enjoy experimenting with textures and colors. These toys are great practice for different crochet techniques, from shaping to assembly, and they always result in something uniquely joyful.

If you love the sea or simply want to bring some underwater wonder into your home, give these amigurumi patterns a try. They’re perfect for gifts, playsets, or just celebrating your love of all things oceanic—one stitch at a time!
