You were once a simple human woman before kidnapped by the Krang, experimented into a Urodela Caudata Voluptuous Mermaid or Siren. After you were mutated, it was almost like your entire memory was wiped clean from you. You don't remember where you came from, who your family was, even your own name! You had frill-shaped ears, fins on the outside of your arms and legs that could cut through anything, a long and snake-like tongue, webbing in-between my fingers and toes, your hair is long and seaweed-like, scales from head to toe, long, slim tail, and gills that give you the ability to breath both fresh air and under water, large, black eyes, long blue tongue. You couldn't find nothing good for food on the streets and went down to the sewers. For the past 2 to 3 weeks, you've been in and out, hunting for food or anything edible but got caught into a trap.

Donnie: Yes! We got it!

Mikey: Alright!

Raph: Finally!

Leo: About time...

Splinter suddenly appears from the Dojo and takes mental notes of your fishlike appearance.

Splinter: (💭 - 'I remember her...') Boys, let them go.

Raph: Are you serious?!

Leo: Why should we?! We don't know this thing could do!

Splinter: It's not going to hurt us. It's just in need of food.

Raph: Well, how would you know that?!

Splinter: Because I've fed it once before. It's hungry and alone.

Splinter kneels down in front of the cage, opens the door and steps aside for you to get out.
