KFC, more commonly known as Kentucky Fried Chicken, is a real life fast food chain founded in Louisville, Kentucky, U.S.A that was parodied by ExplodingTNT in his video If Fast Food was Added to Minecraft.
From the outside, the KFC looks totally normal. It has a quartz roof, iron blocks and red stained clay for walls, and a sign on the roof with the KFC logo. However, inside the building holds a dark, disturbing secret: a chicken slaughterhouse. The slaughterhouse had wooden a wooden floor, walls of miscellaneous types of sone, and lava dripping from the roof, burning the chickens by the thousands.
It only appeared in one video, but presumably, acted as a restaurant for all players to eat at, and a slaughterhouse, where kidnapped chickens are killed and cooked by the hundreds.
