How do I add random rotations to a Character's head to make them appear as though they're twitching

I’m developing a horror game, using a Character that I’ve purchased from the Marketplace. The Character comes with animations that I plan to use, but I want to add something to ramp up it’s creepy factor! Basically, I’m looking to make the head of the Character constantly twitch by adding random values to its head rotation. The effect I’m trying to achieve is akin the the ghost in the PT demo of Silent Hills. I’m kinda new to this stuff, so I haven’t the foggiest idea on how to do this…

Random tick rotation of neck bone?

Would I be able to add a random value to that determined by the animation that’s currently playing somehow? :slight_smile:
