And now, the oddity: this game is getting merchandise. No, seriously, it is, but it's as subtle as it gets:
EXHIBIT A
Well, just Diddy Kong on a Pipe Frame, nothing strange about it… if the pipe frame didn't disappear in Double Dash only to return later in Mario Kart 7, where Diddy had disappeared too!
Indeed, the yellow SNES Pipe Frame is what Mario Kart Tour assigns to Diddy when selecting the combination!
EXHIBIT B
Aaaah, our favorite Mario Kart 7 driver, Toadette! This one is a bit of a cruel addition of salt to the wound actually, considering how, roster apart, Mario Kart 7 was a very fine game actually (and we wouldn't have 8 nor Tour without 7, as both are heavily based on it).
Of course, the standard coloration of the Birthday Girl in Tour is the pink one.
EXHIBIT C
The most subtle of them all! I mean, Bowser Jr. and the Flame Flyer were both in Mario Kart Wii, after all. The Flame Flyer even follows Bowser Jr.'s color pattern, in perfect MKW style!
Well, yes, except that in Mario Kart Wii Bowser Jr. couldn't drive the Flame Flyer, only his dad could! Bowser Jr. could only drive the Wild Wing, the equivalent kart for the medium-sized drivers!
Needless to say at this point, the standard coloration of the Flame Flyer in Mario Kart Tour is indeed this one!
