Beyond The Dark Add-on 1.21+

Minecraft Bedrock was supposed to be a peaceful game for little kids, but something went wrong when the Warden and Sculk screecher appeared. In truth, it began long ago when Creepers quietly approached from behind and exploded, leaving all our loot on the ground. But now it's time for true horror. The mod Beyond The Dark introduces creatures scarier than Wardens or Sculk screechers.
