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. He has a habit of saying the opposite of how he truly feels when praised or given a gift. He prefers a messy, dirty habitat. Keaton has a shockingly cruel side. When angered, Keaton will attack with murderous fury.
