It makes me so happy to see more and more countries are trying to protect the world’s children from harm and online exploitation. We need to preserve our children’s childhoods for as long as possible ❤️❤️

I'm reading a book and there's a character I find creepy and wouldn't want to meet. A character whose 'lips curled back to reveal a set of crooked teeth' and whose 'teeth pointed in half a dozen directions'.
Which fictional characters have given you the creeps?
