Ogre

Ogres are Neutral and Utility Beasts found in the Overworld which seem to be bigger than an Iron Golem. They only come out at Night. There are also some with Two-Heads which are hostile and those with One head which is Neutral and Tameable.

Ogre:
Ogres are neutral mobs 2x bigger than an Iron Golem. They come out at night the same percentage as an Enderman. They are seen holding an Iron Hammer and walk around. If you hit them they will come after you unless you lost them or/and disguise yourself with a Mob Head or Pumpkin. To make them your Utility Mob (golem), you need 8 of any type of Apple. When killed they drop their Iron Hammer.

Two-Headed Ogre:
Two-Headed Ogres are the rares of Ogres and are hostile Mobs. They are the same size of an ordinary Ogre. When they see you they come after you untill you are dead. To make them neutral, you need the Splash Potion of Regeneration and they will become neutral again. When killed they drop their Iron Hammer.
