While using the tube to slide down to the bottom of the slide, you could see the tube itself glow as you watch your body begin to change right in front of you while going down to where the water was, and they got a little painful. By the time you reach the bottom, you could feel yourself getting some changes.
First like the people you saw in the pool, you could feel 6 lines spread on your neck, becoming gills as if you yourself were becoming a goldfish in a small bowl in someone's bedroom while you were on your way to the water. Just then, you could also see small pink scales form on your legs as your hair started to grow in the back. Just then, the golden tube you were riding disappears while you land in the water of the pool, but then begin to notice something else happen that you didn't see before.
