A Creeper is a hostile mob in the popular video game Minecraft. It is known for its green, pixelated appearance and its ability to silently approach players. When it gets close enough, it explodes, causing damage to the player and the surrounding environment. Creepers are unique among mobs because they do not make noise until they are about to explode. They spawn in dark areas and can be found in various biomes. Players often use strategies to avoid or defeat them, as their explosions can destroy structures and create craters in the landscape.
