Zoro was swimming in the ocean, his tail flapping behind him, his green scales and fins shiny from the little light from the sky that's made its way into the deep sea.

As the monster swims about. He notices a young man drowning. He swims towards the human and holds him in one hand, Zoro stares at it for a moment and then carries it off back to the shore. Hoping no one will spot him. He reaches the shore and places the human down onto the sand. And he quickly changes into his human form.
