[iTween] How to get the GameObject to look at the nodes without orientToPath

Now, most of you may instantly think about the parent-child trick for 2D, but I don't think I can use that method. Why? It has to work on a snake... With hinge joint, and all that good stuff. Now I was thinking of using LookTo, but I'm not sure how I'd get it to look at the different nodes.

I'm not gunna rule out orientToPath, but I haven't found any answers that'd work in my situation.

Extra:

Layout of Snake parent. ArmorHead is what needs to move to move everything else like a snake.
