I actually did once think of a fourth season for Captain N. It would explain plotholes like how Kevin's mother never noticed him and Duke were missing (copies of them were put in their places a la The Last Starfighter) and Kevin's gamepad belt and Zapper would've been upgraded into a Super...
I'm livid at how they can't even get names of the viruses right.
Red is Fever, Blue is Chill, Yellow is Weird, WRITE THAT DOWN, NINTENDO.
EDIT: Ah shit, looks like I lied to myself. They were only called by those names in the comic adaptation and I thought those were official. Curse you, Valiant!
By that logic, Luigi on the flyers for the Arcade version of Mario Bros. is not the same Luigi as the one we see today because he barely looks the same.
Yeah, somehow it didn't strike them that Jump Up Superstar would work much better for the credits, especially since the song was used a lot in advertising.
Granted, that was because TAOSMB3 was in production before SMB3's official US release and the Koopalings didn't actually have names in Japan at that time.
