I don’t know how real this video is but it’s more convincing than many of the supposed gray interviews.

If this is puppetry it’s very good, if it’s animation, it is very well done. I am disinclined to believe it’s either, yet the video is doctored with this fake interference both in the introduction and in the video and this detracts from it’s believability.
I have heard from people who worked at S4 that captive grays on Earth developed a bone disease over time that resulted in a hunched over stance, just as demonstrated in this video.
I am curious why this particular alien is unclothed. The one encounter I had 50 years ago involved aliens that were clothed in a suite that appeared to be made up of a metallic fiber, it was an iridescent green like you see on some beetles and other bugs. But it’s skin color was a beige not gray and I can see there some hint of that colorization in this video.
The head shape of the creature in this video is also similar to what I saw and very unlike those in the interview video.
