Happy Friday readers!
What a week it has been, I am very glad that it’s over. Sometime during the madness of writing my mid-term document for my PhD, I found the time to crochet freestyle! And I thought I would make a nudibranch amigurumi. Why not?
So I picked up my hook and I carefully noted down what I did as I went, so that I could share it with you lovely bunch 🙂
Now, what’s a nudibranch, I hear you say? They are marine gastropods, and they look a lot like sea slugs. They come in a bunch of shapes and colours and I think they are the prettiest.

And now without further ado, the pattern. I did my best to make it understandable but it is my first time writing a pattern, so please let me know if it’s unclear, and I’ll try to clarify.
EDIT: if you want to download a free PDF of this pattern, which has been re-written with clearer instructions and more pictures, you can find it on my new website.
I used DK yarn and a 4mm hook (because I tend to crochet very tight, especially when making amigurumi). Tension is not important for this pattern though, using a smaller hook will just give you a smaller toy and vice versa. I used 3 different colours for my nudibranch, one main body colours (MC) and two contrast colours (CC1 and CC2).
Abbreviation list
ch – chain
Sc – simple crochet
Dc – double crochet
Sl st – slip stitch

Main body – worked from top to bottom in the round
With MC
Ch 26 (starting chain + turning ch)
Round 1: Sc in the second ch from the hook, sc 24 (you should now be in your first ch), sc 3 more in your first ch. Sc 24 on the other side of your starting chain, sc 2 more in your last ch. You should have 4 sc at each end ch of your starting chain and 23 sc either part of your starting chain (see photo) – 54 st

Round 2: sc all around – 54 st
Round 3-5: Repeat round 2 – 54 st
Round 6: sc 24, *2 sc in next st* x 2, sc 25, 2sc in next st, 2 sc in next st, sc 1 – 58 st
Round 7-8: Repeat round 2 – 58 st
Round 9: sc 25, 2sc in next st, 2 sc in next st, sc 27, 2sc in next st, 2 sc in next st, sc 2 – 62 st
Join in CC1
Round 10: Ch3 (counts as the first dc), 2 dc more in the same st, 3dc in each st all around. sl st at the top of the first dc. Fasten off and weave in ends
Gills – at the back of the body
This part of the amigurumi is worked in the round. I used the MC but you can also use CC2 if you feel like it.
Using MC, pick-up 8 st in a circle at one end of the body. This will be the base for your gills.
Round 1-3: Sc around. This is the tube at the base of the gills – 8 st
The next step is working on the gills.
Ch 6, sl st in each ch down, sl st back into the ring (in the sc at the bottom of the 6 ch). Repeat 8 times all around the tube. You will now have 8 gills. Fasten off and close up the tube using the long tail.
Rhinophores – antennae-like structures – make 2
This part of the amigurumi is worked in the round.
Using CC2, ch 2.
Round 1: Sc 4 in the second chain from the hook (or sc 4 in a magic circle)
Round 2-4: Sc in each st around. Fasten off leaving a long tail for sewing
Base of the body
The start of the base is exactly the same as the start of the body, except that you start with 21 ch rather than 26.
Using MC, ch 21 (main chain + turning chain)
Round 1: Sc in the second ch from the hook, sc 19 (you should now be in your first ch), sc 3 more in your first ch. Sc 19 on the other side of your starting chain, sc 2 more in your last ch – 44 st
Round 2: Sc 19, *2 sc in next st* x2, sc 20, *2 sc in next st* x2, sc 1 – 48 st
Round 3: Sc 19, *2 sc in next st* x4, sc 20, *2 sc in next st* x4, sc 1 – 56 st
Round 4: Sc 20, *2 sc in next st* x6, sc 22, *2 sc in next st* x6, sc 2 – 68 st
Fasten off, leaving a long tail to sew the base to the body.
Assembly
Sew the rhinophores on, at the opposite end from the gills. Then, sew the base on the body, joining to the MC of the body. When there is only a small opening left, stuff the body and finish sewing the base on. You’re done!
If you do try this pattern, please tell me what you think about it. I hope you enjoy it 🙂 You can find me on Instagram
@emmacraftsdesign I look forward to seeing your nudibranchs!
