In order to capture the sounds of the monsters in Diablo III, the team often turned to recording the sound of real world animals as the basis for the voice/vocal embodiment of otherworldly creatures. One animal that serves quite nicely for this purpose is the pig. During an outing to a pig rescue farm in Solvang, California for a recording session, Joseph met a woman who showed him a pig that played the guitar. After recounting this story to the audience of the Blizzard Sound Panel at Blizzcon 2011, he appealed for attendees to ask Jay Wilson to consider putting in a secret, guitar-playing pig level into Diablo III so he'd be justified in using the sound.
