Minecraft wiki entry for Adventure_survival, associated text: When you first spawn into your world, kill any mobs you come across, except for villagers, but make sure that you leave at least 2 of each animal, for breeding later. Try to sprint and jump as little as possible to save food. Killing sheep can be useful for their mutton, but remember that there is no use making a bed with their wool, as it cannot be placed in adventure mode. You can, however, sleep in beds inside village houses.
