This is a written pattern with multiple photos to show the complete process of knitting the body, arms, tentacles and then stitching the tentacles together and attaching to the body. There are 6 pages in the PDF.
This is a more advanced pattern and you will need to know how to:

Knit in the Round
Knit W&T short rows
Knit Lifted Increases
The Kitchener Stitch
Three Needle Bind Off
Basic Cables
Simple Seaming of knit pieces together

If any of these are new techniques for you, my suggestion is to check out some YouTube videos on each (Very Pink Knits is a great start).

This doesn’t take a lot of yarn to make, so it’s a good project to use up leftover yarns. Also, I’ve knit it from a wide variety of yarn, acrylic, fancy hand-dyed wool, etc and it all turns out fantastic.

I have test knit this pattern many times, but to error is human, so if you find an error please let me know so that I may correct it!
