Used to be that Wiggle Bones addon was a great way of doing so, but the development of it got pretty much abandoned (Twice) and it's buggy as fuck on modern forks, to the point that your preview physics might not ally with what it bakes whatsoever, and it tanks viewport performance to shit.

I still use it but the above issues are fucking painful

I really wish there was some kind of native or optimized simple wiggle implementation without all the simulation fuckery.
