The idea for this animation was suggested by my mom. It took maybe an hour to animate, mostly because of the tail. Didn’t bother adding too much detail to the animation itself because this is basically a meme that I’ll never find use for. 
The implication is that once the Alien catches you, it starts doing this like a gesture in Dark Souls or Elden Ring; essentially it’s the Alien’s equivalent of “Point Down” or “What Is It?”.
Here it is without motion blur…

Rendered in Cycles X. Used 512 samples at 30fps, 2 light bounces with the denoiser turned on. And it took about a minute per frame on a laptop GTX 1650.
