Minecraft wiki entry for Superflat_survival, associated text: The next villager should be a fisherman. You cannot craft a campfire because of no coal in the world, and you cannot make charcoal. However, Apprentice-level fisherman can sell campfires, so you can start to cook food and eat cooked food instead of eating it raw, you can also cook potato to baked potato and kelp to dried kelp using campfire. Also a campfire drops one of the best items ever too, charcoal, that opens up torches as a light source. Place a barrel to transform an unemployed villager into a fisherman.
