A new type of rubber-hose arm/leg system was built for the project to allow for quick costume changes and an unrivaled level of speed and flexibility in the animation process. Rather than some kind of IK system parented downstream from one another relying an a complex system of precomps, pins and control nulls, each limb is controlled by only two layers: one for the base and one for the hand/foot. The system allows you to define the length of the limb, the direction of bend, and the place the control points wherever desired. The system draws a simplified curved between the points, bending when appropriate. This works well for footfalls and grabbing objects.
