What are super balls and where can I get them?

Well, I've finally finished gathering money on the Veldt. I bought six or so Phoenix Downs so now I have twelve. I think that should do for now. I also did buy three white capes. I just bought all three at different times so it didn't 'feel' like I was really going to have to earn another 15,000 gp. Anyhow, I'm off to finish Sabins Scenario right now.
