Zombie

The Zombie is a common enemy that appears during the night on the surface. Zombies attack by walking into you and jumping when they need to get past something. During the night, Zombies will come to your home and try to open the door, although they are unable to (except during a Blood Moon). After the 1.1 update, some zombies have a new texture that features an exposed brain instead of hair.

Blood Moon
When going from day to night, at the bottom left corner a green text may appear that says "The Blood Moon is Rising...". The moon will then look like the red version of the original one. During a Blood Moon Zombies have the ability to open doors, but you can defend from that by placing the door 1 block above the ground. That way they will only jump against your house. Another way to defend from a Blood moon is by placing a block in front or behind your door.
