Duck Reference

For the next animal i am going to try and communicate a Duck through a sphere. I have found these references:



Real ducks moving step by step. Take note of the subtle weight drop on the down which allows the rear to twist left and right with more emphasis.



Donald Duck also does this movement when he moves, this is most notable through the presence of the tail. Notice at the beginning when he is moving left to right between the signs, his feet rotate around the ball of the rear as if he was in water, they moving like mechanical rudders. I'm not quite sure if this can be interpreted into a single sphere but i will give it a go. 



Please see from 4.21 for about 5 seconds! I know, not much, but look how the ducks move. There is a real emphasis on the squash a stretch (only mute, but in comparison) which is more probable for how it will be best to conceive this gesture.
