Ghast

Ghasts are large hostile mobs that will be added in Update 0.12.0 and will spawn in the Nether. They are 4*4*4* blocks in size and have 9 tentacles.

They were planned for Update 0.11.0, but were removed due to them being top buggy. They will be re-added in Update 0.12.0.

Spawn
Ghasts spawn naturally in the Nether. However, in Minecraft Pocket Edition, as of Update 0.11.0, they can only be spawned using their spawn eggs, which are only obtainable through inventory editing.

After Update 0.12.0, Ghasts will spawn naturally in the Nether.

Behavior
Ghasts fly around in the sky, crying at regular intervals. They give out a loud shriek when killed.

Combat
Ghasts attack by shooting exploding fireballs, these fireballs however, can be deflected by hitting it or shooting it with an arrow. Ghast fireballs destroy blocks with low Blast Resistance, and ignite the user and flammable blocks. This is destructive to naturally spawned biome surfaces and user made structures.

Drops
They drop 0-2 Gunpowder and 0-1 Arrows, and will drop Ghast Tears after Update 0.12.0.
