As Tina swims towards the wall, she feels something brush against one of her legs. She swirls around, trying to look down into the water, but finding it too dark to see anything. She paddles in place for a minute, waiting to feel something else brush against her, but nothing happens. Deciding it's her overactive imagination, Tina starts to swim again. She only goes another few feet before she feels something knock against her foot. She spins herself around and looks again, trying to see any movement in the water, but the only waves are being caused by her. Taking a deep breath, Tina dunks her head under the water and opens her eyes, trying to look around and spot whatever it is that keeps touching her. She catches movement in the darkness out of the corner of her eye and quickly turns. Her eyes widen as she catches sight of the creature that's been lurking around her.
