I built my own pig house, and kept my pig for quite some time. A tree monster followed me around ( I was trying to make armor before he killed me, needed more grass). I made the armor, killed the tree monster, but not before he killed my pig. When my pig died, he dropped 25 berries. I assume this is the number of berries I had fed him since I got him. Then, when a new pig came, I fed him the berries for more poop. I accidentally hit him with my weapon, and had to kill him....and he gave me back all the berries I had fed him! Now I have thirty something berries (Had picked some up during all this) and poop, and more pigs! Is this intended, or a glitch?
