The Zoo S01E05 - The Humany Penguin

After being hand-reared, Yoyo the penguin is confused: he thinks he's a human.

Thanks to his identity crisis he doesn't fit into either the human or penguin world, and just when it looks like things can't get much worse, all his feathers start falling out.

Cast away as a ugly misfit all hope seems lost, but what appears a curse turns out to be a blessing in disguise when Yoyo returns to Penguin Beach completely transformed.
