I was lucky to get that trophy when I started playing the game, because after that thing you mentioned above happened to me, I never had to put out a fire again.

I got twins in my 2sd 3th 4t and 5th games but not in my first. However I got triplets in my first game in my 6 gen so got the trophy for the triplets as you know already. But I am still waiting to get the twins in my first game.

Blasted Kung Fu trophy. I had to restart though because my family died out. But I finally got the latte!
