THE ISLAND OF DOCTOR MOREAU AU

After hours of work, decades of study, and one very expensive private island later… You’ve done it! You’ve managed to vivisect medicine’s new modern miracle! The mermaid!

Well, okay, she’s not really a mermaid, she’s more of a fish… person… thing… but it’s the thought that counts, right? Besides, she’s pretty good looking, too.

“Hi!” she says, sitting up on your operating table. Oh, that’s good, she’s still got a grasp of the English language! You’re glad you did the splicing right. “Who are you?”

“I’m Dr. Harley! I made you!”

“Why?” your human/fish friend asks.

You shrug. She accepts this. “Do you want to pick out a name for yourself?”

She blinks at you with those big, goobery eyes. Oh, you suppose you have to teach her about that kind of stuff, huh? Well, you’re definitely glad to do that! You grab her hand, and help her off the table. You’ll probably take her to your private library first, she’s got a whole world out there to start exploring with you!
