The Dummy's appearance is that of most dummies: structured with a head, body, stand and no arms. It is implied to have a cloth-like material composing it (listed as cotton in its check and in Toriel's dialogue after fleeing the dummy) and has visible stitches. It has buttons for eyes, as revealed by its check text. This Dummy can't talk and it's a shy sort. If the Mad Dummy is around they will work for the Mad Dummy because they can relate to being inside a Dummy.
