In Minecraft, players encounter a variety of creatures known as mobs. These mobs can be categorized into two main types: passive and hostile. Passive mobs, like cows, sheep, and chickens, do not attack players and can be farmed for resources. Hostile mobs, such as zombies, skeletons, and creepers, will attack players on sight, adding an element of danger to the game. Some mobs, like wolves and cats, can be tamed to become companions. Additionally, there are unique mobs like the Ender Dragon and Wither, which serve as bosses and provide challenges for players. Each creature contributes to the diverse ecosystem of Minecraft, enhancing gameplay and exploration.
