The whole "shiny" concept doesn't seem to be that big of a deal in the anime...it's usually brought up then dropped just as quickly. He simply said it was oddly colored, or something to that effect, which indicates he didn't even know about it. Since people are always shocked by shinies in the anime, it's safe to assume a lot of people are unaware of the phenomenon.

I wonder if Jimmy will actually be training when we next run into him, or if we'll find him easily swayed into another suck job, like being a Nurse Joy's assistant or something equally mundane.
