in Fire walk with me the arm says " I am the arm and I sound like this " and does a red Indianan style whooping noise, then later when agent Desmond is revisiting the fat trout trailer park you here the same noise when he walks by the electric pole, and later we hear this noise when Gerard pulls up to Leland and Laura at the traffic lights. So when do you hear this new sound that the evolution of the arm makes which is more of a whispy pew pew pew sound. Do we hear it in any of the later scenes ? And if so I sure missed it
