Seeing how the Smash website now allows you to "change costume" when on a fighter's page, I noticed how Larry is the first (or second, technically) costume, and Ludwig is the last. Ludwig is the eldest Koopaling, and Larry is the youngest, (if I remember), but what about Jr.? He comes before Larry, so does that mean he's the youngest of them all? He certainly looks the part. Either he's first because he's the main fighter and all, or he really could be the youngest. Or both. Both works, too.
