1Heat oven to 450°. Stir baking mix and 2/3 cup milk until soft dough forms. Turn dough onto surface dusted with baking mix; gently roll in baking mix to coat. Shape into ball; knead 10 times.
2Roll dough 1/2 inch thick. Cut with 2 1/2-inch round cutter. Roll edges of biscuits in 3 tablespoons milk, then roll in colored sugar. Place on ungreased cookie sheet.
3Bake 8 to 10 minutes or until light golden brown. Remove from cookie sheet to wire rack. Cool completely.
4Split biscuits three-fourths of the way through with sharp knife. Cut 8 tongue shapes, about 3x1 inch, from fruit rolls. Place each tongue on center of biscuit bottom, letting tongue hang out of biscuit. Stand raisins between biscuit halves for teeth.
