Ultimate Walking Skeleton Cowboy

For Halloween, I wanted to make something that looked impossible: a seven-foot skeleton walking around on its own, with an apparently hollow rib cage and nobody inside.

The secret is that I am directly behind it, hidden between two layers of a black cape. A marching band snare drum harness carries the skeleton, elastic loops connect its feet to mine, and small extensions let me control its arms from inside the cape. I also modified the joints so the whole thing moves more naturally.

I gave mine a cowboy theme, complete with a hat, poncho, holsters, and finger guns, but the same basic mechanism could be used for all kinds of characters. Here is how I built it.

Main costume and mechanism

1. 7-foot-tall posable Halloween skeleton (the seven-foot size matters for the illusion)
2. Rigid metal marching band snare drum harness and its drum mounting hardware
3. Assorted nuts and bolts, including a long threaded bolt and nut assembly for the upper-body support
4. Tripod ball joints for the shoulders, if your skeleton has stiff shoulders
5. Elastic for one simple foot loop on each skeleton foot
6. Selfie stick extensions or other simple rods for controlling the elbows
7. Black gloves to hide your hands if they become visible
8. Black fabric, approximately the amount in two full-size bed sheets
9. EVA foam for two cape shoulder supports
10. Zip ties for attaching the cape and foam

Finishing and optional cowboy accessories

1. Black and white spray paint formulated to bond to plastic
2. Small battery-powered red LED light and batteries
3. Additional EVA foam for the cowboy hat, belt buckle, cigar, and holsters (optional)
4. Red fabric for a scarf or poncho (optional)
5. Hot glue and contact cement

Tools

1. Drill and appropriately sized drill bits
2. Tools to disassemble the skeleton and its joints
3. Sandpaper for reducing friction at plastic contact surfaces
4. Heat gun for reshaping the fingers

Exact hardware sizes, EVA foam thickness, and fabric measurements will depend on the skeleton and harness you use. Test the fit before making permanent changes.

I started with one of the seven-foot-tall posable Halloween skeletons sold by several retailers. The height is important: the whole design depends on me being able to stand directly behind it, with my hips roughly aligned with its hips, while the cape hides my body.

These skeletons are made to hold poses, not to walk. Many of the joints have built-in resistance that keeps the arms and legs where you put them. Before I could make it walk, I needed to change that.

I disassembled the skeleton joints and removed the ratcheting parts that normally hold them in a pose. In other spots, I sanded the plastic contact surfaces to get rid of extra friction. I was trying to make the limbs swing freely rather than click into fixed positions.

You do not necessarily need to modify every joint in exactly the same way. Check what is creating resistance, remove or reduce it, and make sure the joint remains securely connected. The change makes a huge difference when the skeleton starts following your movements.

Mine had particularly stiff shoulders, so I removed the original shoulder hardware and installed small tripod ball joints using the existing holes. This allowed the arms to move in more directions and made them much easier to puppeteer.

After helping a few other people build their own versions, I learned that the shoulder mobility varies between skeletons. Some already move well enough. Check yours first; if the arms swing freely, you may be able to skip this modification entirely.

The hands on my skeleton originally faced downward, which looked odd when the arms were hanging at its sides. The hands disconnect at the wrists, so I removed the existing hardware, drilled new holes in the hand/wrist assemblies about 90 degrees from the original holes, and reattached them with the old hardware. That put the hands in a more natural orientation.

I also used a heat gun to carefully soften the plastic fingers and bend them into more relaxed positions. I did this outside for ventilation and worked gradually to avoid overheating or damaging the plastic. Follow appropriate heat-gun precautions and avoid inhaling fumes.

For my cowboy version, I went a step further and shaped the skeleton fingers into finger guns. That detail comes in handy when I add the holsters later.

This is the main support for the costume. I bought a rigid metal marching band snare drum harness from Amazon. It is meant to carry a drum in front of the wearer, which is just the sort of support I needed for the skeleton.

Attach the pelvis

I drilled through the skeleton pelvis and reused the mounting hardware that would normally attach a drum to the harness. The skeleton sits directly in front of me, with my hips at about the same height as its hips.

Set the upper-body angle

I added a second connection higher up to keep the skeleton torso away from my body. I drilled into the skeleton scapula and used a long threaded bolt and nut assembly to connect it to the upper harness near the area where the orange straps attach on my reference harness. The threaded piece let me fine-tune the skeleton angle and the amount of space between us.

Adjust both connections until the skeleton sits comfortably and stays balanced. Before wearing it, check that the hardware is tight and the drilled plastic is not cracking or flexing excessively. The harness needs to carry the load without forcing you to hold the skeleton up with your arms.

This might be the simplest part of the build. I tied a piece of elastic around one of the bones in each skeleton foot, leaving enough room to slip my own foot underneath it. That is the whole connection—no complicated shoe harness.

With my feet slipped into the loops, the skeleton feet follow when I step. The freely moving leg joints do the rest. Adjust the loops so they hold the feet together without being uncomfortably tight or causing you to trip, and test the movement slowly before walking normally.

To operate the arms while staying hidden, I attached small extensions near the skeleton elbows so they reach backward into the cape. I used extensions from a selfie stick and hold them from inside the costume. Moving the extensions lets me move the skeleton arms without putting my own hands out in front.

I will be honest: I do not love my original solution here. The selfie stick extensions worked, but other rods or handles could probably do the job just as well. The important part is reaching and controlling the elbows without showing your hands.

I also wear black gloves. If a hand accidentally slips beyond the edge of the cape, the glove is much less noticeable against the dark fabric.

To exaggerate the hollow look, I gave the entire skeleton a simple two-tone paint job with spray paint made to bond to plastic. I stood on the side I wanted white and sprayed white from that direction. Then I moved to the opposite side and sprayed black from that direction.

That is pretty much the entire technique. The shapes of the bones naturally pick up the two colors differently, giving them a dramatic lit side and shadow side without having to paint every little detail by hand. I did this across the whole skeleton, including the skull, ribs, arms, hands, legs, and feet.

Work in an appropriate spray-painting area, follow the paint instructions, and use suitable ventilation and protective equipment.

The cape is what turns a visible puppet mechanism into an illusion. I used roughly the amount of black fabric in two full-size bed sheets. One layer hangs behind me and the other hangs between me and the skeleton, making a hidden space where I can stand and operate everything.

I attached the fabric around the skeleton shoulders and collarbone using zip ties. With the two layers hanging in place, the skeleton appears in front of a dark backdrop while I disappear into the space behind it.

Loose fabric by itself can reveal the shape of the person underneath. To break up my silhouette, I put two long triangles of EVA foam between the cape layers. I attached them near the same shoulder and collarbone area as the fabric.

The triangles basically sit on my shoulders when I wear the costume. They add just enough structure to keep the fabric from collapsing around me and create a broad, dark background behind the skeleton ribs. It is a simple solution, but it makes the body inside much harder to recognize.

I added a red scarf/poncho around the shoulders for my cowboy. Beyond looking good, it breaks up the shapes around the upper body and helps disguise the person inside the cape. I have seen other builders make convincing versions without it, but I think it helps.

This is an optional styling choice. Depending on your character, a shawl, hood, scarf, or some other outer layer could serve the same purpose.

I placed a simple battery-powered red LED light inside the skeleton rib cage. It makes the chest glow, especially in the dark, and draws attention to the fact that you can look through the ribs and apparently see nobody inside.

There is no elaborate electronics setup here. Use a self-contained light, secure it where it will not interfere with the operator or arm controls, and keep the battery accessible. The red happened to work well with my cowboy costume, but any color could fit a different theme.

The cowboy theme is entirely optional. I made a hat, belt buckle, cigar, and two holsters out of EVA foam. The skull is bigger than a typical person’s head, so an ordinary cowboy hat does not fit well. Other builders have made extra-large hats work, but I made mine from scratch so I could control the size.

My favorite detail is the finger guns. When I reshaped the hands, I made the fingers look like pretend pistols, then gave them EVA foam holsters. It looks funny and sells the cowboy character, but it also gives the arms somewhere to rest when I do not feel like actively puppeteering them.

It also gives me the gunslinger look without bringing plastic prop guns, which are not allowed at many costume parties. You could theme the same walking skeleton as a pirate, wizard, reaper, or anything else you can imagine.

Getting into the costume is easy. I climb inside the cape, put the harness over my shoulders, and slip my feet into the elastic loops under the skeleton feet. After wearing it a while, I could manage the loops myself, but it is easier with somebody helping.

I see through the ribs. Visibility is good in full daylight and decent at darker parties, although I still pay attention to my footing and the people around me. When I walk, the feet and loose joints make the skeleton walk; when I use the elbow controls, its arms come to life. If I want a break from controlling the arms, I put the finger guns in their holsters.

One thing to be ready for is how confused people get about where the person is. They may try to look through the ribs, reach out to touch the costume, or even move the cape to find the operator. Be mindful of that—someone pulling at the cape or skeleton can interfere with your balance. It helps to have a friend nearby in a crowded or dark setting.

That reaction is the most rewarding part. People know there must be a trick, but they cannot quite understand how the skeleton is walking around. The whole costume uses fairly straightforward mechanical ideas, and I hope it inspires you to make your own version.
