“I’ve always wondered where this river might flow. Now I guess I will finally know.” Cleo said with a sigh as she surfaced. All three were strong swimmers and they had no trouble following the current of the underground river as it meandered through dark tunnels. But the lack of light meant that they had no advance warning of the whirlpool that had formed ahead of them. No matter how hard they paddled to try and get clear of it they were no match for the powerful swirling funnel of water. They were soon all so dizzy and exhausted that there was nothing they could do to keep from being pulled down into the center of it.
The whirlpool lines are very involved; you’ve worked hard.
