Zombie Doctor is an achievement for Minecraft that requires the player to throw a Splash Potion of Weakness at a Zombie Villager, then press the right trigger on it with a Golden Apple in the player's hand in order to initialize the healing process, and finally the Zombie Villager will turn back into a regular Villager after 2-5 minutes. It is advisable to build a sort of 'prison' around the Zombie Villager with Iron Bars and a Bed since it will shorten the amount of time it takes for the Villager to be cured by about 4%, speeding the process by 4.8-12 seconds. This achievement is only available on the Xbox, PlayStation, and Windows 10 Editions.
