I saw this video recently on YouTube that was by a Japanese creator, but there was no spoken words. It was like, claymation, of these two little girls playing, and the background is bright yellow and happy, and all you can hear is laughter, and then slowly in the video, black splotches start to appear, consuming the girls, and you can now hear screaming, and I think it was about S.A. 😬

I've been trying to remember to show my friend, but I CANNOT remember... any ideas?
