In the game's instruction booklet it states that the Pols Voice hates loud noises. Consequently, many players mistakenly believed this to be a reference to the game's recorder item, and were surprised to find that the instrument had no effect on the creatures. The text only applies to the Japanese version of the game, as the Famicom's (Japanese NES) second controller had a built-in microphone. By talking into this mic you can effectively kill the Pols Voice.
