Richard Williams animating animals, squirrel run cycle.


Head moves with and aginst the front foot.
Tail moves with the back legs.
Head goes down slightly when front of body goes up.

Legs and arms move opposite each other (just like human arms in a walk cycle.)
So the chest is up (passing) while pelvis is down (contact)
Pelvis moves allot more than the shoulders.

body folds and unfolds. Moving in waves as the weight transfers.
Squirrels are very flexible, so its quite obvious.
