Picture of Brain Slug Plushie + Pattern

[monotonous] "I got you an official Bender hat."

The Brain Slug is one of my favorite creatures on Futurama, and quite possibly one of the easiest and most fun Halloween costumes I've done in a while. What's not fun about talking in a monotone voice, and if it falls off your head you can loudly exclaim, "I'm free of that nightmare!"

You'll need a few hours of time, and a basic knowledge of sewing to complete this cute little Brain Slug plushie.

Step 1: Materials and Pattern

Picture of Materials and Pattern

  • Fleece (bright green)
  • Black and White scraps for the eye
  • Green thread
  • Pins
  • Scissors
  • Needle
  • Sharpie marker
  • Sewing Machine (optional)
  • Printer (for the pattern)
  • Stuffing (Poly-Fill)
Cutting the Pattern:

When you print out the pattern be sure that you don't shrink the image in any way. The image is already sized to 8.5 x 11, and reducing the size to "fit to margin" or anything like that will make things smaller than we want. Once you have the pattern printed out and cut up, you need to cut out some fleece for your Brain Slug.

You'll need:
  • (14) Feets
  • (1) Bottom
  • (2) Side Piece
  • (4) Antenna

Step 2: Antennae and Feets

Picture of Antennae and Feets

Start out by sewing two pieces of the Antenna together by using an overcast stitch. These are really skinny, and we wont be able to flip them inside out, so I decided to use that stitch since it's somewhat decorative, and I just like how it looks. I did the same thing for the Feets, except I wound up flipping those. These should all be done by hand, since they're so small.

Once you're done, you should wind up with a pair of Antenna for the Slug, and seven little nubby feet thingies (which I will still call Feets).

I just wanted to say THANK YOU! This pattern and the directions worked perfectly! I now have two brain slugs ready for the invasion!

Only change I made was using a googlie eye instead of a felt one.

Nice job!
Someone asked me how I put my brain slug on a head band, and I suppose it might interest other people too, so here are my tips :

*get the plainest and thinnest headband you can find. I used a thin black plastic one.
*before sewing the bottom to the sides (it is easier, you can do it once the brain slug is finished but it is tedious), cut a rectangular piece of fleece a little larger than the headband and sew along the lengths under the bottom.
*ensure the headband can go through it. Most likely the tube you have sewn will be too large and the brain slug might slip down, if so make another, tighter seam, keeping the headband in. You don't really have to undo the first seam.
*the tube should be tight enough now to hold the headband while allowing it to be taken off.
Nicely done!

Just in time for Halloween.
I love it and already made 4 for friends who happened to pass by and loved the one I had made for me.
I found the first one too big for my head so I made the others 75% of the original size. I put a little filling behind the eye and added a strip of fleece under the slug to attach a headband.
Looks great!
I also put some plastic from a Coke bottle in the antennae to keep them stiff.

How much green fleece is needed in total.
Like whats the minimum?

I wanna make one but I have no other uses for green fleece.

Awesome instructable

If you fit everything together perfectly, the smallest you could go is a 1ft x 1ft square of fleece. I would suggest using more than that, like a 2ft x 2ft square, just for some leeway.
