The Mine Little Pony mod adds new player models and textures that make players look like ponies in inspired by the show “My Little Pony: Friendship Is Magic.” Once the mod is installed, you and all other players with a special pony skin will look like ponies in both singleplayer and multiplayer! The mod is adjustable to allow players without a special pony skin either to appear normally or to show up as background characters from the show.
