I sadly have no photo to kinda help out, or even if it was Chinese or Japanese (most likely Chinese if I remember), all I know is that there was a post that had a TV report on an Asian mother with Multiples, delivering by C-Section, mainly in Gifs, and you could literally see the Babies moving around.

I swear there was a post, but I can't find it :/

Found an image related to this, hope this helps.

Found it in my MEGA collection, but it might not be what you remember.
