Hi all,
I threw together this example earlier; nothing fancy, mostly default settings.

The interesting bit is how Stiffness controls the “tension” of each spike, wheras Damping governs how rubbery they feel.
Another interesting bit is that in this scene, anything gray is Kinematic (completely animated) in which case I found that the arm would get trapped in the spikes. That’s a good sign your animation probably can’t perform the action, so to accommodate this I temporarily turn the arm into a Dynamic arm such that it can respond to being trapped. It eventually frees itself, at which point I animate the arm back to Kinematic.
