“Ghasts are very large, jellyfish- or ghost-like mobs that float through the air and shoot fireballs from their mouths. They are lava and water resistant. Their bodies are 4 blocks tall and 4 blocks wide with 9 tentacle-like limbs hanging from the bottom and eerie-looking eyes.”
Ghasts spawn in the Nether, with at least 5x4x5 space.
Ghasts will shoot fireballs at the player when they see you. You can hit the fireball back at the Ghast. Like all other Nether creatures, Ghasts are lava resistant. They are water resistant too. They can also come to the Overworld if you make a big enough Nether Portal.
