I don't have any screenshots of this video, nor have I found anything about it on the Internet. It had a Japanese title with some English words (I think it had creature in the title). The video consisted of several clips of a family at home, and in these clips a small stick figure (I think it was a stick figure) appeared. It would pass by and hide from the camera, and sometimes someone would see it. It's probably from before 2016. I don't think the creature had dark tones. I think one of the scenes was in the kitchen. Actually I'm not sure if it was in Japanese, it could be either Japanese, Chinese or Korean.
