Ghostbusters Slimer Costume




I have wanted to make this costume for a while and kept putting it off.

So this year I decided to go for it....with only 4 days until Halloween and a budget of just £30.

To make my costume I needed the following:

  • Hard hat
  • Chicken wire
  • Garden wire
  • Cable ties
  • Old Newspapers
  • Lots of PVA Glue
  • Cotton Wool/Tissue paper for sculpting
  • Ping pong ball
  • Stiro foam blocks
  • Green Spray Paint.
  • Hot Glue Rubber
  • Garden Gloves
  • Yellow and Pink Acrylic Paint
  • Clear Spray Varnish

Step 1: Building Your Frame

Firstly to get the initial shape I bent some garden wire to shape the mouth and attached this to the hardhat using cable ties. I made the mouth a little bit bigger so I can still have visibility when wearing the costume.

I used the same garden wire to sculpt the initial shape of the head and the body.

Once I had an initial outline of the body, head and mouth, I used chicken wire to fill the gaps in between to help make the structure more solid and sturdy.

I used cable ties and sticky take to help secure the chicken wire - you might want to wear some rubber garden gloves when working with the chicken wire.

Keep trying on your costume during this process - making sure it fits right and to ensure good visibility.

Step 2: Paper Mache Time

Once I secured the shape with chicken wire, it was then time to start with the paper mache.

For this I used regular PVA glue, diluted a little with some water to make it go further. Because I had used chicken wire I only needed 2 layers of paper mache - it's entirely up to you if you want to do more. I was pushed for time as I only had 4 days to make this.

In my opinion the paper mache dries better in a well ventilated room but I speeded up this process by leaving it next to the radiator :P.

Step 3: Slimers Face

Once the layers were dry I then started sculpting the face, for this I found using cotton wool for the cheeks, brows and lips was a quicker and more effective way of doing this.

I found the nose a bit more difficult to do so I used tissue paper instead to sculpt the nose as this was a little more intricate.

The eyes were simply made from a ping pong ball cut in half and hot glued into place.

The teeth were cut out of some styro-foam I had lying around and again hot glued into place.

Remember nothing has to be done perfectly, it is slimer after all and the more uneven everything looks the better the finished result.

Once everything was in place I gave the whole costume 2 more layers of paper mache but using white tissue paper - this meant my costume only needed one layer of spray paint to stop the newsprint from showing through.

Always try giving the costume plenty time to dry between layers of paper mache. Some times leaving near a radiator or in a well ventilated room can help speed up the process.

Step 4: Time for the Fun Part - Painting Slimer!

I then spray painted the whole costume a lighter shade of green. I used a darker shade of green to add some detail and shading. I used some pink acrylic paint for the gums, yellow acrylic paint for the teeth and eyeballs.

To make Slimer look a bit more spooky I decided to give his eyes orange pupils with black rims using coloured foam sheets cut to shape which were then hot glued directly onto the yellow eyeballs.

Once the whole costume was dry, to give it a bit more protection I gave it a light coating of spray varnish.

During the process it's good to have something to stand the costume on while it dries between all the different stafes; for this I used my cats scratch post = she wasn't very happy but I promised I'd buy her something nice if I win a prize hehe.

I wore all black clothing with this costume to make it look like slimer was floating when I wore him. I wore a long sleeved green top for arms and green garden gloves for the hands.

Step 5: The Final Result!

And so here he is - all finished and made within a 4 day time frame.

I took Slimer out for a night on the town on Halloween and despite all the poking and prodding from people loving the costume he arrived home in one piece - I was very surprised myself!

This is the first time I've done such a detailed Instructable, I should have taken more pictures along the way.

I hope you liked my idea and appreciate any feedback or comments and of course if you decide to try making your own Slimer then please let me know!

    This is an excellent costume. Great idea, and very well executed!

    You should separate your photos into steps and share the details of how you made this in a step-by-step fashion. That'll make this a bit easier to follow, and greatly help your chances in contests! ;)

    Good luck!
