Boneys

In Warm Bodies there are two types of zombies: fleshies and boneys.  Fleshies are the typical zombies portrayed in the zombie genre, however boneys are a new phenomenon.  When first reading Warm Bodies, I found the boneys to be comical since they are simply skeletons walking around. However, as the story progressed they actually became more terrifying.  Even though they do not look human anymore and are just bones, they represent humans at their core.  Since the boneys do not like change and in a sense are evil, it makes me think, are we evil at our core?  Is this how society fell in Warm Bodies because of who they became?  Another terrifying aspect of the boneys is the strange humming sound they make.  It is a sound so far from being human-like and it builds up anxiety in the characters and the readers.  It makes you question your purpose as a human being: are we leaving the world to allow it to prosper? or are we causing its downfall?
