Passive mobs are non-aggressive creatures found in the game Minecraft. They do not attack players and often provide resources or benefits. Examples of passive mobs include cows, sheep, and chickens. Players can interact with them to gather items like meat, wool, and eggs. These mobs typically spawn in various biomes, such as plains and forests. They play a crucial role in the game's ecosystem, contributing to farming and crafting. Unlike hostile mobs, passive mobs can be bred, allowing players to create a sustainable source of resources.
