It's him, Chopper Artbong(the blue mouse/cat) with Lunarotte, his father, a monster cat. Whoa, is him his father? Well, yes, he can transform himself in whatever he wants, and he decided in this scene to turn into a kid of the age of his son. Chopper is the only living being Lunarotte could love, despite being sad of the idea he's more the appearence of a mouse than a cat like himself, but that happens to mess around with a female mouse some years ago.
Chopper could go deeper into his own story, if you want to know more about those two characters, contact him.
