Zombie Villages
Villages have a chance to spawn as Zombie Villages. In this case, they will consist of Mossy Cobblestone, Vines and Cobwebs, and Zombie Villagers will spawn in place of regular Villagers. They don't contain any Doors or torches.

Trivia

 * Although the chances are extremely low, there is a chance that a Village may spawn in an Old world.
 * Some Villages can rarely generate together, creating double or triple Villages.
 * Often, when this happens, Grass Paths and buildings may overwrite structures from another Village.
 * Sometimes, Lava in Blacksmiths can flow through the house at Village generation near spawn.
 * There is a fixed bug in which the Blacksmith building would burn down due to the lava kept within cobblestone by the entrance.
 * Villages are currently the only sources of fully grown Beetroots.
 * However, not all Villages generate with a Beetroot farm.
 * Biome-based Villages were added in Update 0.15.0, as well as Zombie Villages.
 * There is an Android-exclusive bug in Update 0.15.0 where the Stronghold entrance spawns on surface, replacing the Well and sometimes causes world crash upon quitting the world.
 * Either that or only the Stronghold staircase spawns underground.
 * Bug: In Update 0.11.1, farms won't spawn.
 * Large Houses in Taiga Villages generate with a single chest containing crops.
 * This is due to the fact that Crops don't grow very well in Taiga Villages.
