Guides
Easy Manure Farming
 * Step 1: Get a pig to follow you.
 * Step 2: Use your whole day to collect flower petals.
 * Step 3: Make a fire pit and make sure the pig sleeps.
 * Step 4: Give all the flower petals to the pig while it sleeps. Next day it will give you manure corresponding to the amount of petals given to it. (Note that you can also use other things to feed it with such as berries and butterfly wings.)
