This is one of the coolest things I’ve seen – a mechanical wolf tail that moves by itself! The costume piece straps around the waste with a belt, then moves based on movements from your legs, hips, or shoulders depending on how the tail is designed. The end result is natural tail movement when you walk – or even when you are standing, depending on how it’s operated – that looks eerily real. The tail movement is so realistic and unexpected that it’s really hard to stop looking at it as it sways back and forth, shakes, or pulls up.

While some people use the animatronic wolf tail as an addition to a halloween costume, others use it during the rest of the year to express themselves, and sometimes simply to have fun. Most of the mechanical wolf tales are handmade. A selection of videos is below showing different types of tails in use from different angles, while the last one shows how to make one yourself.

Here’s a really good video showing a moving tail. The wearer associates different positions with different moods, just as a wolf might.

Here’s a pretty good video that shows how to make the animatronic wolf tail, step-by-step.
