The Red Eyed Stalkers

This mod adds red eyed villagers, and pillagers to your world which ruin villages, and stalk you from behind trees, and in your caves.
The red eyed villagers are primarily the stalkers, which watch you from tree tops, caves, behind trees, villages and in every biome. They have a small chance of attacking, but will stalk you until you look at them then inflict blindness, and play many cave noises increases the haunting ambience.
The red eyed pillagers have a much more rare chance of spawning, but when they do when you see a red eyed pillager it will instantly attack (50/50 chance whether it will attack or vanish). They are a much more agressive, but rarer variant of the red eyed villager.

This mod does not remove regular villagers, or pillagers.
Use the /summon command with cheats on to spawn in a red eyed villager, or pillager (although they will spawn automatically, more so at night and in thunder storms but also in day):
"/summon red_eyed_villager"
"/summon red_eyed_pillager"
