His Mother's voice (Mom traded)
No arms (first go)
Sally's blond curly hair (Zoe felt like giving it too him)
Zoe's Breasts (courtesy of Mikey)
His Mother's mouth (courtesy of his father) keeping his own as well, he was able to talk with both voice at the same time saying different things, a very unique feeling
His Father's legs (his own trade, when he lost his)
