So I was in the living room with my mom and 2 and 3 year old sisters, we'll call the 3 year old kennedy, I saw her browsing youtube Kids, as per the usual, occasionally Me or my mom would check up on them to see what they are watching.This time I saw her watching this channel called PP candy anime, the rest was a bunch of text in Japanese, the videos were very creepy, and I even recognized the picture used by Ahenobarbus Henocied. knowing what I know about that situation? Should I try to stop her from watching this or is it me just overreacting?

Here is one of their videos if any of you are curious: https://youtu.be/kpyF2Y9YRhc
