Cheerful, albeit a bit dense about human social standards, Keaton does his best to impress others or make them happy, even at the cost of his own happiness or potentially his life. He's interested in things others would normally find to be garbage, gross, scary, or creepy — ranging from a dirty old doll to arachnids to human remains and beyond. He has a habit of saying the opposite of how he truly feels when praised or given a gift. He’s also pretty sensitive and tends to tear up when hurt.
