First tentacle:
Now crochet 3 and 2 single crochet stitches alternately into a stitch link in each of the 10 chain stitches, starting from the first stitch after the hook. This means 3 single crochets in the first stitch link of the chain of chain stitches and then 2 single crochets in the 2nd stitch link of the chain of chain stitches, then 3 single crochets in the 3rd stitch link of the chain of chain stitches and 2 single crochets in the 4th stitch link... and so on until all stitches of the chain of chain stitches have been crocheted. This will form a tentacle spiral.
More tentacles:
To crochet the next tentacle, make a slip stitch in the next stitch of the body and repeat step 2 from now on until your octopus has enough tentacles. So once around the lower edge of the body, making a total of 5 tentacles. When you have finished, you can secure the thread with a slip stitch and pull it through the stitch, but do not cut it yet!
Fill the octopus:
Now fill the octopus with stuffing material. Make sure you use the right amount and do not overfill or underfill. The filling material should not peek out through the stitches!
