The narrative implications of major world cities depopulated (from humans,) then repopulated (by toads,) and repurposed as race tracks in the switch mario kart game are quite disturbing when you think about it for a sec. Did the mushroom kingdom invade earth at some point? How did it get here?

Come to think about it, wasn't the 80s cyberpunk Mario movie set in New York? Was that what happened after they'd been occupying us for a few years? Much to think about.
