you do realize Im a GFX artist not a Gani artist. That gif animation was just a demo. If you want it to sway left and right and get bigger and small and bounce like a real life one, tell the gani artists that. Also, i highly doubt the gani artists will try to make the damn pixel toy mimic real life natural law of physics 9 times for a jack in the box toy.....

this is pretty much the extent of the animation. sorry it doesn't obey the natural laws of physics in real life.
also I have included the springs and the heads of the creatures so the gani artists could make it "sway" or "act more like a spring" if they wanted to. again, im the gfx artist, not the gani artist...
