That's weird, I think it must be some kind of scaling issue, I didn't set the scale mode.
@ JAC!
The skeleton animation is computed realtime with sines rotating the bones back and forth, there is no physics involved though. I used some derivative of the walk sine speed for rolling the objects over the surface to create the illusion of movement. The parallax scrolling was done by setting random speed multipliers (~1) for every object, the multiplier range determines the percieved amount of depth.
Thanks for the wonderfull comments and the votes all!

If anyody is interested in the code let me know and I'll clean it up a bit before posting.
