First Mario or Luigi must climb up its leg to get to its head, with several Bullet Bill launchers on it and gears, then get one Bullet Bill (likely from one of the launchers on its head) to hit the cage on top of his head. Then the cage should regrow so get another Bullet Bill to hit the cage then lead it inside the cage to hit the container with the Grand Star.
