The Kneecaps, I think, are key. One of the things I love about the design that was left out of the original Bandai Monkeys, or any other transformable design I can think of for that matter. The pivoting kneecaps are a great piece of armor that likely needs some kind of mathematical formula to drive the pivot and aniimation in regards to the mid leg portion and the lower leg.
Great idea if that is what you're talking about, DOK.
