I see people talking about their dreamies on here fairly often, but how did y'all pick them?

There's only one villager I'd consider a dreamie for myself. It's Aurora and that's only because it just so happens that I had a stuffed penguin toy (penguins are my favorite animal) that I had name Aurora several years ago, so once I saw that Aurora was a penguin, of course I have to have her.

Side note: I seem to recal someone here making some kind of program that helped you pick what villagers you wanted. likee you put in species and personality and it pulled up all the matches or something like that. anyone remember that? It was how i found Aurora in the first place, but i forgot to save it.
