two objects moving around with mouse

I'm making a catching game and I only wanted the falling objects hit certain area on my catcher. My catcher is a girl with mouth open and I wanted the falling objects to hit only the mouth, not any other parts of her body like arms. So I made two objects, the full girl and just the mouth. How do I make the two objects (movieclips) move around with the mouse?

I tried to embed one object into another but it didn't work....

This is actionscript I wrote so far:

package {

    import flash.display.*;

    import flash.events.*;

    import flash.text.*;

    import flash.utils.Timer;

    import flash.utils.getDefinitionByName;

    public class CatchingSkittles extends MovieClip {

        var girlmouthfront:GirlMouthFront;

        var girlmouth:GirlMouth;

        var nextObject:Timer;

        var objects:Array = new Array();

        var score:int = 0;

        const speed:Number = 7.0;

        public function CatchingSkittles() {

            girlmouthfront = new GirlMouthFront();

            girlmouthfront.y = 258.00;

            addChild(girlmouthfront);

            setNextObject();

            addEventListener(Event.ENTER_FRAME, moveObjects);

        }

        public function setNextObject() {

            nextObject = new Timer(1000+Math.random()*1000,1);

            nextObject.addEventListener(TimerEvent.TIMER_COMPLETE,newObject);

            nextObject.start();

        }

        public function newObject(e:Event) {

            var goodObjects:Array = ["Red","Purple","Yellow","Orange","Green"];

            if (Math.random() < .5) {

                var r:int = Math.floor(Math.random()*goodObjects.length);

                var classRef:Class = getDefinitionByName(goodObjects) as Class;

                var newObject:MovieClip = new classRef();

                newObject.typestr = "good";

            } else {

                r = Math.floor(Math.random()*goodObjects.length);

                classRef = getDefinitionByName(goodObjects) as Class;

                newObject = new classRef();

                newObject.typestr = "good";

            }

            newObject.x = Math.random()*500;

            addChild(newObject);

            objects.push(newObject);

            setNextObject();

        }

        public function moveObjects(e:Event) {

            for(var i:int=objects.length-1;i>=0;i--) {

                objects.y += speed;

                if (objects.y > 425) {

                    removeChild(objects);

                    objects.splice(i,1);

                }

                if (objects.hitTestObject(girlmouthfront)) {

                    if (objects.typestr == "good") {

                        score += 5;

                    } else {

                        score += 5;

                    }

                    if (score < 0) score = 0;

                    scoreDisplay.text = "Score: "+score;

                    removeChild(objects);

                    objects.splice(i,1);

                }

            }

            girlmouthfront.x = mouseX;

        }

    }

}
