They're both in my brother's town which I'm about to reset soon. Offer something, I'm trying to get bells saved up to buy Lolly, my last and final dreamie. If you want to offer Lolly for either one of them, I'd even be willing to give extra bells or art.
I have actually been trying for almost a week on another forum to trade Fauna for Tia. I can TT to Fauna's moving date in my cycling town if you would let my daughter pick up Tia. It would be about an hour before she is home though.
This is not a site I have used before. I've just been a lurker but I have made many trades on another Animal Crossing site.
