I really loved Antonio in my Wild World town. One day I didn't realize I hadn't gone to speak with him as usual (for the first time ever....just my luck) and the next day, he had moved out. I'm hoping to get him back in New Leaf.
Anchovy was my first dreamie, although not sure if I got him first. I based my dreamie list mostly off of villagers that I already have, because I really like most of them. I also just kinda grabbed some villagers here from TBT that I decided to get.
But Anchovy was my absolute favorite villager when I played WW in first grade. I don't know why I liked him so much, but I still think he's pretty adorable. It can be kinda hard to find the low-tier villagers here..
The first dreamie I obtained in New Leaf was Scoot. I remember when I first started playing, I saw him in a person's town and instantly thought he was way too adorable and that I MUST have him in mine. In order to get him, I lurked online and found communities like Belltree and ACC to help me find him. Thankfully, after my long-awaited search I was able to get him in BellTree. n___n Though at one point, I was so scared I wasn't going to end up getting him because of the fact the trader and I had busy schedules.
My favorite dreamie overall is Punchy, I was lucky enough to have him as an original resident when I first started playing.
