A snowman is an anthropomorphic snow sculpture often built in regions with sufficient snowfall. In many places, typical snowmen consist of three large snowballs of different sizes with some additional accoutrements for facial and other features. Due to the sculptability of snow, there is also a wide variety of other styles. Common accessories include branches for arms and a rudimentary smiley face, with a carrot used for a nose. Clothing, such as a hat or scarf, may be included. Low cost and availability are the common issues, since snowmen are usually abandoned to the elements once completed.
