What i never understand...
With any of these movies with zombies or creatures that hunt by sound, i dont get it. How do they know what sounds to attack or react to?? Water rushing, fire crackling, leaves and trees blowing, them themselves moving and attacking are making noise and they dont confuse themselves nor any of the others. To me it sure seem like they'd bumble around confused and attacking about anything.
And you tell me that friendly cat never purrs or meows?
Since they are attracted to sound, you just keep rocks or small hard things in your pocket or bag to throw and distract if they get close or if you accidentally make noise.
