A Ghast is a hostile mob found in the game Minecraft. It resembles a large, floating cube with a white, ghostly appearance and is known for its distinctive, crying face. Ghasts spawn in the Nether, a hellish dimension filled with unique landscapes and dangers. They are capable of flying and can shoot explosive fireballs at players, making them a formidable opponent. When defeated, Ghasts drop Ghast Tears, which are valuable items used in crafting potions and other recipes. Players often encounter them while exploring the Nether, where their eerie sounds can be heard echoing through the caverns.
