Troy was a royal. That meant he needed to act like one, which he didn't.

He'd always sneak out and swim off to the surface somewhere.

Until one day, he got especially close to the shore. As he took a look at it, he noticed another individual sitting there.

A fox? no.. a human? no.. something in between.

It seemed that the creature was trying to catch a fish without any luck.

Troy dived back down and quickly caught a fish, then surfaced and threw the wiggling fish to the fox-human.
