The Scientist Pig Doctor Patrick King who is also the brother of Steveyo Trashy King. this mod adds Patrick as a mob to spawn in and have around as a friend.
Use a spawn egg or command /respawnpat to get him in the world, tame him with a right-click and have him follow you around, and have him stay where he is by using a carrot on him.
This mod is very low skilled and buggy so use with love.
