I did this a lot with Pekoe. Like a lot.
Basically, I saw a picture of Eunice the sheep and immediately decided she was a dreamie. I tried to get her online, but to no success. It happened again with Papi a few days after.
Soooo, I ordered the two amiibo cards online, and I knew exactly what I wanted to do. I had nine villagers, and wasn't Biff's biggest fan. I didn't hate him, I just never fell in love with him! And he moved in where I was going to put an Inn, and in Bertha the hippo's place. Biff was also a hippo, and Bertha was the first to leave my village, so I was quite sad when she did.
But in the wait for the amiibos to arrive, Margie moved in from my friends town and messed up my plan. So someone else had to leave. I decided on Pango, my original peppy. I do miss her now, but Winnie is here so that's good.
Anyway, Papi's amiibo arrived first. I scanned him in and said my goodbyes to Biff. I was shocked Biff was leaving straight away but he packed up and headed off, and Papi was set to move in. Papi moved in right next to where Biff was, so the inn found a new spot as Papi wasn't leaving. Then I scanned in Eunice and said a difficult goodbye to Pango, who planned on moving to the big city and making her fortune as a famous celebrity actress. I wished her luck, and Eunice moved in.
I was pretty happy with this for a while, but it occurred to me that I now had three normal villagers and no jock villagers, so I needed to do something about that to get my fire pit! I love penguins, so I want Roald. I still haven't got him, if I get nothing online I'll buy his amiibo too.
I let Pekoe go, she'd been here longer, she asked first, and Margie was from my friend's town which got broken. Even if Margie messed things up for me a little, I did like her. I found Pekoe a nice new home as a dreamie in another town, and I might go visit her soon. But it took me a long time to decide to let her go!
And now I'm on the fence about something else! Diana, my original snooty who has only asked to leave maybe twice in an entire year, my town's age, told me Chadder was considering leaving! I was wondering what to do, considering Chadder moved in two days after I started, but I saw Julian not long ago at the campsite and decided not to let him move in as I have a smug and my one space is reserved for a jock. But now Chadder is thinking about leaving himself, I might go back, it was only maybe last week, and pick up Julian from my campsite. I'll see what Chadder says if I say he can leave.
Thanks for bearing with me, that was very long!
