Farming in Lime Odyssey will give you the opportunity to harvest crops or livestock in order to receive various forms of loot. However, you will have to pay attention to various aspects around your farm in order to ensure happiness and success. That means your crop must be monitored, fed or healed to increase its level of satisfaction.
Once the crop or livestock has reached the level of "greatly satisfied", you will be able to harvest it. In some specific cases in Lime Odyssey, the reward may actually be a "jackpot" reward, offering up rare recipes, gear or even greater quantities of the normal yield.
