Mr. Resetti was created to avoid the use of the reset button.

If you don't know this peculiar guy, you're lucky. Perhaps one of the most annoying characters found on video games, Mr. Resetti lives up to his name, every time you reset your console when playing Animal Crossing you'll get a visit from this mole. He might seem cool, harmless and even cute but if you manage to piss him off you’re in for some trouble.  If you think he isn't serious, you're wrong, he means business reset one too many times and he'll threaten you with resetting your game (actually he never does but one never knows).

He is one of the most righteous characters in the Animal Crossing universe, every time he shows up he'll give a lecture on why resetting is a bad thing , he'll make think of your actions, he will even say you are a bad person and if that wasn’t enough you can’t skip it, once you’ve summon him there’s no turning back, so be advice fellow gamer thou shall not reset thy game. He doesn't lack moral fiber, he is moral fiber, and his job is to keep cheaters outside of the game. So if you still think you can get away with resetting your game when something bad happens think twice, Mr. Resetti might be on the look-out.
