Ancient Creatures
The mod “Ancient Creatures” for MCPE brings back and introduces ancient, long-forgotten legendary beings into Minecraft Pocket Edition. Most of the newly added mobs are significantly more dangerous than their predecessors, which means that downloading this mod for MCPE will also increase the challenge of the game. Pharaohs, giant cobras, and flying skulls are just a few of the creatures you will encounter in Minecraft PE thanks to this mod.
