Hoppers really hop
Kangaroos, rabbits and frogs get their own Walk, Run and Run2.
Creatures on the hopper body plan now move with a hop cycle of their own: they crouch on landing, push off, pitch the nose up in flight, tuck their legs, pump the tail and land again, with the ground moving under the feet at the speed the clip claims.
Run and Run2 are the same cycle, higher and faster. Frogs no longer stand on stilts.
