User blog:FoolishMortalFOOL/Help! How to name this Devil Fruit

Since there was a hito hito no mi which gave Chopper the ability to partially or fully transform into a human.

I am trying to make a devil fruit that gives a person or object turn into a merfolk but there's a problem.

What to name the devil fruit?

Hito Hito no Mi: Model Merfolk

(Human Human Fruit: Model Merfolk)

or

Sakana Sakana no Mi: Model Merfolk

(Fish Fish Fruit: Model Merfolk)

I know that Merfolk are not human and they are not fish either (I believe that in the world of OP, nobles and humans had referred Fishman and Merfolk as fish which seems and is insulting to them)

So what you guys think?
