heisenberg uncertainty principle - NO Uncertainties for particles in their own frames!

Well I had this thought experiment in which a particle observes itself, and something like the following is observed.

Taking in mind the uncertainty principle all particles even stopped at 0K jiggle about, but nothing stops us from going into there frame and observing from there. We do just that, we go in the frame of a particle and keep it at the origin, since we are in the frame of the particle it does not move, its entire universe seems to jiggle as from outside frame we would say the particle is jiggling.

So how the principle seems to have failed here? We most definitely know that our particle is motionless at the origin when we see from its own frame, we do not care about the entire universe jiggling about and we notice that the uncertainty principle becomes invalid! Why is such a thing happening? Am I doing something wrong? Or is this a known loophole to the principle?
