In Case You Missed It: Pols Voice (The Legend of Zelda, 1986)
(Published on November 20th 2016)
The Legend of Zelda manual lists out some of the enemies Link faces on his journey. One of them is Pols Voice, where it says he's a ghost with big ears. It also mentions he has a weak point, loud noises. If this sounds odd to you, it's because the second controller on the Famicom in Japan has a microphone. In the Famicom version you can kill Pols Voice by yelling into the microphone. Even though we didn't get a microphone in the US, they still mention the loud noises in the manual.
