Hamphrey is sweet! He's nice to Tom's character although it did take awhile for him to warm up to him. The best way I've found to get cranky villagers to love you is speaking to them in moderation.
I had Fuchsia before while cycling and she really grew on me. By then I didn't have my second copy of the game so unfortunately I had to void her. :< I was really happy to get her back though~
No way about Bonbon though, what are the chances haha. I didn't even really know what she looked like until you mentioned her and I googled her. She is pretty cute though. As for Marshal, I feel like he constantly says the same things as Julian. He even changed his catchphrase to "glitter" and they're in the same shirt now. Granted, one is a tiny white squirrel and the other is a tall blue unicorn and 6/10 of my villagers are wearing that shirt, I have to spam conversations with those two less because they keep dancing/telling me I look cooler than a fair number of cucumbers ;__;
