You just sit there for about an hour, thinking about what your going to do, and then the mosiac fish start to glow again, then sudenly your hands start to itch, then scales form on them, and a scaly webbing grows inbetween them. You watch a the scales start moving down your arm and stop at your elbows. You back starts to hurt, then with a painful rip, it stops. You feel you back and realize that you have a fish fin on your back! You relize that unless you find a way out your going to turn into a fish!
You hear footsteps aproching, so you dve down again, and swim to the other side of the pool, and then you think you can feel a faint cack in the wall in the shap of a door! You try to open the door, and it barly opened half an inch.
You start to think that you should see who's coming, on the other hand, they might not like the fact that you used their pool.
