I know it's adorable and cute! But in the episode where KO and his friends become animals, they go to this place where animals can dress as humans and humans can dress up as animals, and so KO and his friend dress up their human selves and that's the end of the episode. So that means that they are still animals for the rest of their days. And it's a sad one too. I didn't mean to make someone sad or angry, it's just the truth and not a theory or fiction
