I can't remember my Wild World villagers (I played it before I attended school and only played it twice before dropping it) but in City Folk Puddles was my first peppy too! I was experimenting with the net and bonked her over the head a few times and she got mad. Woops. I can't remember much but she yelled at me to go catch some bugs, but not hit her.
When I first started Squirrel, Bonbon took it however.
Mine was Tabby, she was in my town when I arrived.
I don't really have any dreamies, allow most of my villagers to move in naturally and try find something to appreciate in each of them... but I never really liked Tabby. I really wanted to love her, but I find the peppy characters a bit annoying even when they're adorable... so loving Tabby was a bit of a stretch for me.
