I grew up with a cartoon from Czechoslovakia known as pat and mat which I loved and watched before I saw anime

I have seen pictures of it before and it looks terrifying.

that's just an image, you're not even explaining. please explain with actual words

Something about them just seems eerie. It feels like i used to watch it even though i never have.

ok, thx for your explanation. I have the same ideas when I was young, like when I first saw anime like patema inverted back in 2016, it felt like something familiar and popular amoungst teens even though I never saw anime before and i think it was deja vu
