Sans appears as a relatively short and paunchy skeleton, with mitten-like hands. Sans is always seen with a wide, toothy-grin on his face. Sans wears a blue hoodie, a white t-shirt underneath.  He has white dots in black eye sockets that disappear when he is serious or angered. Sans is lazy, often sleeping on the job and taking breaks. His laziness is a combination of fatalism and apathy, he loves his couch, sleeps all the time. He make puns all the time. A lazy punmaster.
