What is your favourite and most hated monster in don't starve?

For me, the favourite enemy is probably deerclops. He was destroying my bases when i was a noob but i just like this guy, he is somewhat interesting and also he was the first boss introduced in don't starve. And for the most hated enemy it would be hound, these little guys always attack you in the worst situation, when you are really low on health. So i was wondering what are your favourite and most hated monsters in the game.
