Quoted By:
The most misunderstood of all Pokemon, Zubat is a small, nocturnal creature that dwells in caves in large colonies. Zubat have no eyes, but can use echolocation to find their way around.
To understand what this is like, try closing your eyes and navigating to the bathroom using only the echoes of your highest-pitched scream.
That is how the Zubat do.
