As you start walking away from the lake, your shoes start to feel a little tight. As you have been walking for some time you ignore it, but the tightness increases, as if your shoes are getting smaller.
Finally you can bear it no longer, and sit down on a nearby rock. As you start to remove your shoes you see that your hands are green and webbed! You stare at them for a few moments until your shoes remind you why you stopped. Reaching down, you see that your pants are at half-mast, and your legs underneath are green and hairless. Grabbing your shoe, you tug and tug and when you finally get it off, you see your foot is now a huge size 29 flipper, ripping open the end of your sock!
