" Isn't my sister the coolest? " - Sans Sans is a lazy kind of guy. He likes to takes naps everywhere and to any time of day. This guy is not one for the hunt, since he absolutely hates walking, let alone running. Instead he absolutely loves telling jokes, especially puns and has a strange obsession with ketchup and hot dogs. Sans loves pranking people - tokotas and humans alike. Even his "sister" isn't safe from it. But don't think you can fool around with his sister like he does. Sans is quite protective of her, despite his small posture in comparison to her. He will end you if you dare to hurt her. Besides Papyra his best buddy is "aunt" Diana since she loves puns and bad jokes as much as him. Still he is not comfortable with her around his "sister" since Sans believe Papyra is too innocent for Diana's morbid or dirty jokes.
