I soon found it easier to hop rather than walk, and the mermaid weighed less than I remembered. Eventually we came to a large lake. "Will fresh water do?" I asked.
"It will surfice." she replied. "Now, throw me in."
I tossed her in with a splash. "I sense you have a good heart despite your mischievious mind. You were unaware of my true self."
"Does that mean you'll turn me back?" I asked, sitting on the bank and dipping my flippers in the water.
"That depends. In the meantime, why not come for a swim with me?"
"I er, can't swim very well." I replied.
She grabbed my flipper and dragged me into the deep water! "You will in your frog body! Being an amphibian you'll be able to hold your breath too!".
I was dragged down to the deepest part of the lake. When she finally let go I swam up to the surface with suprising speed. "That was amazing!" I cried.
"I knew you'd pick up." she replied "Fancy a few laps?"
I agreed, and for the next few hours we swam around the lake. Despite being half-fish she could hardly keep up with me!
