When we jump, at mid height our feet tuck in, and move forward to make contact with landing. We tuck in; find our balance and lift make up; this happens rather quickly depending on the force of the jump.
As we run both feet lift from the ground, for split second. We keep travelling through the air.
Head of the Ostrich and Big Bird; both animals’ heads bob up and down as they walk. They also sway left and right as they walk. Jonas’ neck should therefore bob up and down as he walks (slightly); and because of his short feet, and long handle he would sway left and right as he walks.
