Only upgrade weight

The Dung Beetle creates fertilizer and oil when he poop are in inventory. It must be wandering to produce. To remain at that spot, place it in a cage on a foundation (ceiling = drop)

After you use them for fertilizer and oil for awhile they will get hungry. They eat spoiled meat :)

Get yourselves a Phiomia as well! Feed it stimberries and you'll have plenty of medium feces to throw in the dung beetle. Fill it up, and come back and watch more fertilizer than you can imagine. I'll never use compost bins again!
