Naturalist

The naturalist is a scholarly human in the world of Minecraft and the fictional writer of Minecraft: Mobestiary by Alex Wiltshire. He has supposedly made it his life’s work to study Minecraft’s mobs and write his finds into an encyclopedia about the creatures and animals.

Minecraft: Mobestiary
The Naturalist explains how each mob works in detail according to his perspective in the Minecraft world. Most of the writing focuses on the in-game mechanics of each mob, but occasionally describes or shows information from outside of the game. Such as the origins of the killer bunny, TNT shown inside a creeper, and the superstition of the chicken being a spy. There are also dissections of some of the mobs showing organs, bones, gas, magma, gears, and/or redstone depending on the mob.
