I've got a basic rigged character that I'm hoping to instance on ground geometry.

The thing is, it has a basic 2 bone chain with the child bone using a ‘look at’ at a null constrained via a sticky to a animated geometry. The premise is that topmost geometry is controling the look at (its the flower bush system from my previous post), so i can animate it deforming and the flower heads would follow.
Generaly i need to make a animatible bush that is controlable in shape. And the flowers need to open up and close but that is not the problem for now. Any suggestions are more than welcome.
