Zombie

Attacking the player
Zombies spawn in groups of 4. They pursue the player on sight from roughly 40 blocks away, as opposed to 16 blocks for other hostile mobs. The detection range of zombies is reduced to half of their normal range (20 blocks) when the player is wearing a zombie mob head.‌Zombies periodically make groaning sounds, which can be heard up to 16 blocks away. Zombies attempt to avoid obstacles, including sheer cliffs and lava, and try to find the shortest path toward the player Unlike skeletons, zombies do not try to avoid being hit and continue to pursue the player even when being attacked. Zombies can sometimes deal damage through a closed door, as shown in the picture to the right. Zombies sink in water, facilitating their transformation into drowned.
