The Creatures Time Forgot Pt. 1

Three girls. One night. Three tails?

One night in late July, three girls go to their friends island. But what they don't know is that they will become the only Mermaids with red, turquoise, and black tails. The other mermaids' tails look like goldfish.

They have to continue their lives normally, except for the fact they can't touch water. If they do, instant tail.
