Cats Are Mean, and dream cats are no exception. But in reality, Pluto wasn't dreaming. He really did go to Hell, where the evil Cat Prosecutor, an evil agent in cat form, and his cronies tormented the dog. Thankfully, the High Council rescued Pluto from Hell before the cat demons got him with the Hot Seat by warping reality to make the whole excursion seem like nothing more than a dream. The cat prosecutor gets his souls through mock trials, and is very successful at it.
