-Tammy and Sheldon were my first two (neither are favorites of mine, Tammy is cute but there are so many ursine sisterlies I prefer)
-Merry (had her for MONTHS and did a big photoshoot when she left, I just downloaded Pocket Camp and she's now my... manager thing in that, she is just utterly delightful)
-Erik (also kept him for months, such a cutie, and I actually preferred his starter house over his "real" one when I saw it online)
-Megan (didn't realize she was new, but found her rather boring compared to the tons of incredibly precious normals out there)
I remember them all well, though most didn't last long. Except Merry and Erik ☺
(controversial opinion: Merry is the best peppy cat and kicks Rosie's tail)
EDIT: OH! And my first forced camper was Graham. I was super excited because I had him for awhile in ACNL and I just think he's such a cute smug. My BFF, though, upon seeing I had him was like "I'm so sorry" and I was so confused
I guess there's a solid amount of online hate for him? But I love him and kept him for quite awhile!
