A snowman is an anthropomorphic snow sculpture often built by children in regions with sufficient snowfall. In North America, typical snowmen consist of three large snowballs of different sizes with some additional accoutrements for facial and other features. Common accessories include branches for arms and a rudimentary smiley face, with a carrot standing in for a nose. Human clothing, such as a hator scarf, may be included. Low-cost and availability are the common issues, since snowmen are usually abandoned to the elements once completed.
