A flying hostile mob that looks like a human-faced bat that appears in a new cave.
This mob has the ability to pass through most blocks.
And when it finds a player, it quickly rushes to the player and attacks the player.
This mob attack gives the player nausea and slows movement.
This mob is a dangerous entity hidden in a cave unlike Warden and Creeper.
If you have any other good ideas, please let us know in the comments.
Thank you for taking a look at my idea.
