You're curiosity gets the best of you as you walk through the shark door. Inside you find a large pool with several fish inside but no shark. You suddenly feel an irresistible longing to jump in. You strip down and dive right in.
After swimming around for a few minutes you realize something is wrong. Your skin is tingling and looks whiter than usual. You begin to realize something horribly bad is happening as your hair falls out. You then notice your legs. They’ve taken on a bluish gray hue and the skin is unnaturally smooth. You have no idea what’s going on for a moment but then it hits you, you’re turning in to a shark. And almost to confirm this new revelation your legs and feet begin binding together.
You attempt to swim back to the edge of the pool, hoping that this will stop once you exit when you feel the worst sensation you’ve ever felt in your life coming from…your crotch. You stare in horror as your penis and balls smooth out and begin shrinking. You clutch on to them, trying desperately to preserve your manhood but it’s no use, they melt together into a single, featureless lump of flesh which is quickly absorbed and assimilated by your tail. You examine your tail and notice the last remnants of your toes disappear.
Your changes appear to slow down but it’s not over yet. You’ve since given up trying to leave as your arms are losing their strength and shrinking. Your hands are utterly useless globs of skin and dissolving bones. There is no way you’re getting out of this one. Your neck swells as gills form and your face pushes forward. Your teeth are forcibly removed from their position and replaced with sharper, stronger teeth. Suddenly those fish look quite appetizing.
