I've seen people play Minecraft in YouTube videos and make their Minecraft character like, dance. They are able to lay down, move their shoulders side to side, sit down on the ground, etc. Is there a way I can do this in Vanilla Minecraft? Or do I have to install a mod? Also, I'm in Minecraft PC 1.12.2.
Sorry if this is unclear, if it does come out that way I'll change it ASAP.
