In my honest opinion, Hazbin Hotel is not a show for kids under 14, although I barely turned 14 I discovered Hazbin Hotel in 2019 when it came out, so I was 12 when I watched it. I still loved it considering that my parents just allow me to watch inappropriate things in movies, plus learning how children were born at 10. It really wasn't a big deal for me but I still would not recommend 13 or younger kids watching the show.
