a rather low and "wide-boned" skeleton, whose hands very much resemble mittens. He is always seen with a wide toothy smile on his face. Sans wears an unbuttoned blue jacket (or sweatshirt) with a gray hood and a white T-shirt underneath, black shorts with white stripes, and a pair of slippers[1]. His black eye sockets show white pupils that disappear when he is serious or angry. When using telekinesis, an iris appears in Sans's left eye, flashing blue and yellow.
