How to put R15 animations onto a NPC???

I've looked up regular animation tutorials but in the end they don't help with my specific request. I've tried recoding the animation scripts on a player but they are far too complicated for my level of coding. I'm stumped at this point so I've come here. How do I put the exact R15 animations of a player (ex: /e dance) onto an NPC. Here is script I've tried using, but I realized I can't do it this way :P:

 -- Animations
local animationOne = script:WaitForChild('AnimationOne')

local animationTwo = script:WaitForChild('AnimationTwo')

local animationThree = script:WaitForChild('AnimationThree')

local humanoid script.Parent:WaitForChild('Humanoid')
local dance = humanoid:LoadAnimation(animationOne, animationTwo, animationThree)
dance:Play()
