Veganism

Due to the abundance of vegetable foodstuff it's entirely possible to play the game with a vegetarian or vegan Blockhead. There's no need to kill creatures for food.

Leather and fur can be scavenged from dropbears and donkeys that die of natural causes, so your Blockhead can still make leather and fur items, albeit slowly. Dodo feathers for making the Tyrian Purple pigment or a soft bed can be acquired the same way.
