Test your nerves with the Creepy Mobs addon, which injects a dose of gore into Minecraft. This addon transforms familiar mobs such as villagers, chickens, and zombies into creepy versions, their appearances drenched in blood. It's important to note that these changes are purely visual, as their behavior and damage remain unchanged. Additionally, a few new mobs have been introduced, including the notorious Herobrine and the eerie Siren Head.
