Drop down into the hole

You decide to take the new tunnel below and carefully drop down. As soon as you hit the water, you notice it is unusually warm. You begin to swim towards the edge of the pool but stop to look down when you feel something touch your foot. You let out a small yelp when you see hundreds of thin worms slowly rising from the bottom of the pool. Splashing frantically, you swim as fast as you can trying to get out of the water before more of the worms reach you, but as you near the edge, you feel a sharp pain inside one of your thighs and then another on your foot. More and more worms begin to bite you and by the time you get out of the water, you have at least twenty of them hanging off of you. You feel nauseous seeing them attached to your body but at the same time, they don't seem to be harming you any more and trying to take them off might be dangerous.
