“Tail Sail! Buy 1 Merfolk tail get 1 free.”
That was the sign hanging in the window of the “Mermaid’s Tail” shop. This was a sale which happened every year and every year many couples, friends and even whole families show up to get a really good deal on some very high-quality mermaid/merman tail swimsuits.
Unknown to them, a selected handful had been pre-determined to cause the one who buys them into merfolk. Since it was a buy 1 get one sale, any tail or tails since there was no limit on the number of tails if a group of six people came and all bought a tail each, if one of them was the magical one they would all change.
“Are we ready?” asked one of the workers.
“Yes.” Confirmed another as she touched a small mermaid necklace. “How many people are we suppose to turn into our kind this year.”
“It depends, we go off what we need in our world.” Said an older man who was acting as the manager “Also fate will help us decide. Now everyone get into positions, the doors are about to open and with any luck in a few hours we will be welcoming our new brothers or sisters into the sea.”
Who is walking into the door to buy a tail?”
