Minecraft Mobestiary: An official Minecraft book from Mojang

Written by a naturalist who has made it his life's work to study Minecraft's mobs, and illustrated with field sketches, Minecraft Mobestiary is the definitive guide to every mob in the game. You'll find little-known facts about passive, neutral, hostile, utility and boss mobs, as well as more general information about their location, behaviour, threat level and drops.
