Favorite Mods?

This one's for you longtime Minecraft fans.

My favourite mod from back in the day would have to be More Creeps And Weirdos. It added so many new elements to the game, some things i remember from it were thieves that steal your things, pyramids with mazes and prizes, aliens, hampsters, invisible people, giant letters, mob bosses, zebras, dog people and so much more. Just recalling it makes me want to reinstall forge and relive the nostalgia.
