I only have one pig and he came from Hunting Roaming Bandits. He is a pinkish looking fellow (or lady). He is my only animal that does not make a sound. My sheep baa, my cows moo and my chickens cluck.
I see many neighbors with various types of piggies. Do any of them oink or snuffle or does my poor pig have a speech impediment? He does seem quite happy regardless.
