A couple of favorites:
I didn't think I'd care much for Dora (the mouse) at first, but by the time she said she was moving out she had become one of my favorites. Unfortunately I was on a trip irl and didn't get to talk to her on her last day! I felt guilty, haha.
Bruce is the deer on the top right; a "grumpy" type villager. The way he was always wandering the town with a shovel at 3 AM and living in a garage led to a running joke that he was a serial killer. He's still wandering around town at night, but he tends to be watering flowers nowadays. He always seemed like such a quiet, polite boy.
