Outer Sans

Sans wears a hoodie that has fluff inside it everywhere, with two yellow stripes and yellow sleeves, and he wears fluffy slippers with stars. Sans has a supporting, caring personality. Sans also likes puns and tells them so much to the point that it annoys his younger brother, Papyrus. Outertale Sans is also sometimes depicted as a bit shy. but you are in a train that is floating around space (idk, the pic gave me the idea)
