But... Didn't Flea have pink hair?

Though it is worth noting that the "Flea Vest" you receive from Flea was not originally a vest. It was actually a "Flea Bra", but was censored. I recall a description of the Flea Vest being "makes him look more feminine", or something along those lines... Though I do not recall from where this description originates... Perhaps it was from Chrono Cross?
