adding player animations to NPCs?

I have a perfectly working Mr Bad Guy Jugg 1000 hp sword swinger, Which already has one animation for when it is swinging the sword. Now I want to make the NPC to have the normal, animations of a player on it but I don't know how to, I've asked this question as the others confuse me as of lack of answers, understandable answers and the wiki just makes it even worse. Please explain and show an example. Sorry but this question has no example of what I have done to be given. Thank you.
