Strange sounds in the village

I can go to several villages, it is hard to find a blacksmith. However, when I went to a blacksmith's voice, suddenly found that the lower right corner shows "zombie: roar" during the day, "skull: chuck" and the voice of the spider (world) at that time, I want to know to walk around the blacksmith turned a circle, not to find the monster. I think voice is broken, and then opened the computer voice, surprise, really heard the sound of a monster. At that time I didn't want to and soon left the village. Found at the end of the next village village blacksmith, and found that the "zombie: roar".
