Original 3DS, original Auqa Blue color.
I believe I got it in the same month it came out, and dang is it worth it. The free ambassador virtual console titles are sweet.
Its still blue, but now it has a snapped hinge on the right. I'm being careful not to break it off, there were a few close calls. When its Christmas i'll be getting a new one.
since i wanted a teal one (which arent being produced anymore), my mom had to get one from amazon and so, i had acnl for a while before my own 3ds......
Funny story actually, I bought a 3DS to play Animal Crossing on at the same time as I bought the game. I had a nice blue one all picked out as blue is my favourite colour when the sales clerk walked over and asked if I needed any help. I told him I was going to buy this, upon which he snatched it out of my hands and put it back on the shelf saying: "No, no no! You want the green limited edition Yoshi one! I'll go to the back room and get one for you" and I was too surprised and he was too quick for me to say that blue was my favourite colour.
