I'm trying to create a very low poly, 2D tree that uses square pixels as leaves. I have animated the tree and I'm now adding leaves. I'd like to make the leaves shake with the tree's animation and then, gradually, fall off.

I've tried doing this by attaching an emitter to an armature, but I can't make the emitted objects follow the movement of the bones. Any advice on this? Maybe I have to do this through another method entirely.
