Minecraft wiki entry for Villager, associated text: NPCs are villager-like mobs in Education Edition and in Bedrock Edition if "educational features" are turned on. NPCs can behave almost like players. They can also chat to players, turn their heads, and even rotate their body 360 degrees. They are the only companions to chat with in a single player game. They can't move, even when hit. NPCs cannot be pushed, but are affected by gravity. Breaking a block under an NPC causes it to fall like an armor stand. Using a bubble column on a NPC makes it go up.
