Yarr Cute Crowd Models is a mod that is responsible for changing the appearance of the vast majority of Minecraft monsters, turning them all into girls. These girls have an anime look. It is therefore a purely visual mod, since in reality it only modifies the design or appearance of mobs in the game, but not their functionality.

With this mod installed, villagers will continue to trade and iron golems will continue to attack enemies, only they will look like anime girls. The same will happen with Creepers, Zombies, etc. So, even if you like anime, try not to approach monsters with confidence, because they will continue to have the same desire to kill you as they always have.
