Heat oven to 350°F. Cut cookie dough into 14 slices, 1/2 inch thick. Roll each slice into a ball. On ungreased cookie sheet, arrange 7 cookie dough balls in circle 3 inches apart and 2 inches from edge. Securely insert 1 craft stick into each ball, with end pointing toward center of cookie sheet. Repeat with another cookie sheet and remaining 7 cookie dough balls.
Bake 12 to 15 minutes or until golden brown. Cool 2 minutes; remove from cookie sheets to cooling racks. Cool completely, about 30 minutes.
Meanwhile, divide frosting among 4 bowls. Leave 1 bowl of frosting white; color remaining bowls with purple, green and blue food colors. Frost cookie pops; decorate with icing and candies as desired to form monster faces.
