Tentacle Tutorial

How to make some really creepy tentacles. The first pair took me approximately an hour, including figuring out what I wanted to do. The last pair of this lot of twenty prolly took me about 10 minutes once I knew what I was doing.


All up, these twenty tentacles prolly took me about 5 hours.


What you will need:

  • One pool noodle (remotely flesh-coloured) for every four tentacles you intend to make
  • A Whiteboard Marker
  • A knife with a back-bevelled blade (so it’s almost square ended rather than pointed)
  • A pair of gardening gloves and enclosed shoes.
  • A retractable stanley knife that you can extend a fair bit of blade from
  • One pair of skin-tone panty-hose for every two tentacles you intend to make.
  • A pair of sharpish scissors


Firstly, find the balance point of the pool noodle, and cut it in half. You can find the balance point in the picture shown later on, or you can just guess at this point. Organic stuff isn’t exact.

Next, mark the centre of the text on the pool noodle if you have it. This will provide a reference point to shave it a bit later.



Now, mark the opposite end of the pool noodle on the bottom. You can easily guess this by putting the text far away from you on top, sighting along the noodle, and then marking the bottom. Do not mark any nearby cats (shown).


Now you really do need to find the balance point. You can do this by putting the text up and holding the pool noodle between middle finger and thumb, as shown. Mark the points where your middle finger and thumb balance. You’ll prolly get marker on you by this point, and this is why you use whiteboard.


This is approximately what half the marked noodle should look like.


Then, trace a half spiral down from the top in each direction, so you end up with a flared base at the bottom (forming the point of the opposite tentacle). It doesn’t matter if it’s exact, but if you try to aim the line to the marked points, and turn the noodle as you go then I found I got a better line than trying to move the pen up and down.



Firstly, put on the gardening gloves and closed-toed shoes.

Next the cutting. I found a stanley blade to be too sharp and flimsy for this, cutting into the opposite side and making it the cuts too jagged, which I didn’t want. I also found that if I angled the knife down, sawing from the inside of the tube, and relying on the knife’s backward’s bevelled tip to avoid cutting the opposite side, I could do this fairly quickly, especially if I rotated the tube, rather than the knife.

I also tried to do both cuts at approximately equal times, sawing down a bit on one side, then the other, relying on the tube to hold the cut in place until I was finished. You’ll see what I mean.


I then cut away some of the extra edges which I thought might be sharp, and bevelled the top of the noodle, so that it was a bit more flush with the arm. The stanley knife really comes into its own here.


Not everyone held the tentacles like this, but it’s what I initially thought of.

I have tiny wrists. I slipped it over my forearm like a sheath, and then lined the inside with some paper tape I had lying around on the first few, but for most of them I didn’t bother.


Finally, get the tights, and cut the them in half at the crotch (not pictured), forming some stocking with loose tops (Which will be used to cover people’s hands and secure to people’s wrists.)

Then get your tentacle, and put the stocking on as if it were a pair of socks, starting from the tip.

It should be starting to look appropriately gross-looking.


A picture of my test tentacles.  This is what the final product of a pair of stockings looks like. The tights have been separated, but you could make icky crab claws the same way.
