All my perfect match trophies were just pure luck, as were most of the rarer bugs. My first perfect match I didn't even know I had it until the trophy popup - I was a noob and it was second gen on my second family. I didn't even realize how rare it was. Now I pause the game before I read a proposal email to re-check their job title, desire for kids and verify which trophies they need - gosh what a change. hehe
I never even saw my first dragonfly; I only saw the sparkles.
