I have Jeremiah, Punchy, and Zucker (all lazy) on my island at the moment, as well as Flurry and Marcie (normal). I can say for sure that I will never tire of hearing "a huh huh huh" 20 times per day. Unfortunately, I still don't have any snooty villagers.
i guess some people don't like overly cheerful personalities, but i never get the hate that peppy villagers get... they make me LOL with their delusions
