NO! In smb3 cartoons, they LIVED in Brooklyn, but they were now living in the MK, they even had a house there.
Mega, answer me this: if they were born/raised in Brooklin, why are they called Mario and Luigi? Why do they like pasta? How, then, could Luigi bring Mario back of that 'robot' state (in wich the scientist koopaling put him) using a plate of SPAGHETTI WITH MEAT?? UH!? I still remember Koopa's (I mean, Bowser's) son running away of his father with that plate on his head.
