Genuine question. Has that laugh always happened when interacting with Mr. Peeks' headphones? Also, I managed to interact twice with the headphones in Astrid's shop and they disappeared; they also disappeared in the PhD area. This one was the only one that apparently didn't disappear.

Does anyone know the locations of the other boxes? Also, do we have to use the Farrapinho field upgrade somewhere on the map? Since that mag at the lighthouse has it.
