One thing that puzzles me... Now, the last game the Koopalings were in, Mario&Luigi, they looked like their old selves, still "kids" I guess... But would they be "grown-up" by now? I mean, they haven't changed much...
People rarely age in video games or cartoons.... I say that because I can't think of a logical explanation. I didn't really like the song in "King Scoopa Koopa", it was, surprisingly, dark.
Really? My YouTube is working... I just listened to it and you were right Sir Grodus... That song is quite dark... It says something like "watching the bridges burn" or something, which I don't understand...
Also of note, the Donkey Kong Country cartoon had the spontaneous song thing too, except the characters actually sung them instead of mostly having them as background music. On a sidenote, all of Kaptain Skurvy's songs rocked, seriously.
