Bat

Bats are agressive flying creatures. They can fly over water and 
their speed is greater than hearthling's running.
==Combat Strategy==
Bat can be killed in one shot from Hunter's Bow.
Find a single bat, target it from ~15 tiles range and approach slowly using Ctrl+LClick.
Shoot at an appropriate distance, around 4 tiles.
This can be done with less than 10 Marksmanship skill.
It is possible to comfortably kill a bat with 20 Unarmed Combat and 25 Agility without taking any damage. Assemble a combat deck with 2 Quick Dodge, 2 Punch, and 1 Jump. Keep your green and yellow defenses up at all times (Yellow is especially important as the bat will use a strong yellow IP attack periodically) and punch the bat until it is dead. 
==Notes==
*Bats do not attack "Batmen" as of update "Burning Harmonica"
*Added in update "Without Batting an Eye"
*Bats will aggro even at crawl speed, although the aggro range is much smaller.
*Cleaned Bat can be spit-roasted for Intelligence, Perception and Agility FEP's.

*You can prevent bat spawning by paving the cave tiles.
*The quality of a dead bat is hardcapped by Survival of the hearthling who killed it.
