Life or death

You don't understand why parents leave their fry before they even hatch and leave them and their siblings to survive by themselves.
You don't understand why sirens only ever eat human meat.
You dont understand why your pod refuses to share food equally, often leaving you with no food.
And most of all, you dont understand why your pod, your only family, left you.

You are the runt of your pod of siblings.
When an attempt to get food goes wrong your siblings abandon you and you get captured by pirates.
You didn't expect the crew to be entirely animatronic.
