She just seems so... Meh to me. It's nice when she starts to become more friendly with you, but that's as far as your contact with her goes. There isn't even any scenes of her talking to anyone else.
Probably Lyle. I'm still mad at him for selling me insurance in wild world. He's gotten a lot better, but I do wish he'd just get to the point sometimes instead of taking forever when he talks.
Digsby gets points for being particularly bland. Isabelle also gets a mention because I find her to be really bossy and annoying at times.
I agree with you! Shrunk has never felt like he fits in the game. I know he's one of those axolotl lizards, and is a legit animal, but he just doesn't feel right...
Again, I hate to be a Sally Do-gooder, but I don't dislike any of the special characters. I think they are all an integral part of the AC family. If anything, I feel sympathy for them. It can't be easy having ME as their mayor, LOL!
