At the beginning of the game, Rover asks you some questions. The answers you give to those questions determines what your characters face will look like when you enter your town. What face did you receive?
Here's a list of all of the faces:
Just say what area of the list you are on.
As for me, I was the number one boy character on the top of the list, I might reset though.
I'm boy version third one. I looked up the face guide before I started though. Wouldn't want to end up with "It's a secret!- I'm moving there-yup!" xD He looks like a psycho.
I got the girl version two, mainly because I liked it the best. Naturally, if I didn't think about it, I'd be the first one, but when I actually thought about it I came out as Number 2. I like it the best; my eyes are blue (naturally, without colored contacts) and I like the hairstyle!
