Sans never expresses surprise or confusion. When Asgore asked him what flower would remind Toriel of the time she and Asgore first met, Sans responds that he should probably 'talk to his plants.' Despite his carefree personality, Sans gives good advice to those who need it. Sans enjoys making jokes and puns, as shown when he interacted with Toriel in his store after she forgot the eggs she brought. It is notable that he deeply cares for the well-being of his younger brother. He also seems to be amiable towards Kris and eager to interact with the citizens of Hometown. Sans appears to be a laid-back character who enjoys messing around with others for his amusement. Sans also possesses white glowing pupils in his eyes, depending on the sprite. He wears a blue unzipped hoodie, white shoes and black shorts. Sans appears as a short, paunchy skeleton with a wide smile and large eye sockets.
