Benjamin. Okay, here me out. He moved in without me expecting it so I couldn't plot reset or villager reset, he destroyed my path right in the middle of my town and took out my pine trees. When I tried to remove him I ended up losing Marshal in the process. Whenever I see Benjamin I just get mad haha. He left though within a week. Worst of it all was I didn't even snag his sloppy furniture.
I think all the mice villagers look really scary to me. I had Penelope at one point and I couldn't get over how scary she looked. XD idk, there's just something about them.
I loathe Clay. He moved in unexpectedly and destroyed some of my hybrid flowers and my paths. I'm currently trying to get rid of him but he's so stubborn it's frustrating.
Marshal. At first I was hyped because I knew I'd make some big bucks off him (best random move-in ever).
Then he moved right on top of my perfect orange patch, and better yet his house is freaking UGLY.
I had squirrel soup that night.
CROQUE OH MY GOD.
He's the bane of my ACNL existence, he's the ugliest little frog I've ever seen, and he refused to move out even after everything I haven't done for him. I hate him so much, he's mocking me with his existence omg.
Klaus has been my least favorite for a very long time, but Monty moved in my new town and OMG , I couldn't stand that little monkey. He finally moved out a few weeks ago. I didn't really like Harry either.
