Direct implant, probably held with some kind of pouch/wires
Here I've tested the crane movement and an couple steps. I will have to make sure all the components match the realistic weights of each part as it moves. This is just a test but it's given me a good idea of what to keep in mind as i'm animating the final model. Hydrolic legs and a heavy machine body will have to coincide with the light fleshy fetus and work together.
