The "Monsters from the Backrooms" mod adds highly detailed monsters from the Backrooms. There are 7 monsters in total, but I plan to add more in the future. Each monster features unique sounds and animations to enhance the gameplay experience!
Note: Monsters do not spawn in the world; they are available only in Creative Mode under the "Spawn Eggs" tab.
