	public class BankMucus extends IParentCommon
	{
		protected var body:Body;
		private var sprite:MovieClip;
 
		public function BankMucus()
		{
			body = new Body(BodyType.KINEMATIC);
			body.shapes.add(new Polygon(Polygon.box(35, -35)));
			body.align();
			body.userData.tempSpeed = 0;
			sprite = newSprite()
		}
 
		protected function newSprite():MovieClip 
		{
			return  new bankMukus_mc();
		}
 
		override public function init(e:Event):void
		{
			super.init(e);
 
			sprite.scaleY = 0.8;
			this.addChild(sprite);
			this.addEventListener(Event.ENTER_FRAME, updateSprite);
			this.addChild(new KillGroundUnit(sprite, body));
		}
