Mob Battles Mod Installer description
By default mobs won’t fight other mobs in Minecraft Pocket Edition. It gets kind of unfair when they constantly try to go after the player but never try to attack one another. That’s why Mob Battles
Mod Installer for Minecraft Pocket (MCPE) was created to make it possible for you to turn two or several mobs against each other with the simple use of an item called the Orb of Anger.
