Lol. You win, good sir.
Didn't knew how to spell F.L.U.D.D correctly, here in Italy it's called " SPLAC 3000 " (don't ask me what it means...).
Also, don't take timelines so seriously.
After both their adventures, Luigi gave up on being a janitor to honor the plumbers' world with his presence again.
But he couldn't know about his brother's new gadget, because Mario was on vacation.
Then he entered Mario's house, saw the cathastrophic situation, and left to became a janitor again. There, served.
This or I am drunk.
Lucario vs F.L.U.D.D? After that, Luc would stink like a wet dog. Period.
