I really believe he's only living there for the pandas on earth. This episode shows the balance on Mr. Villain's work and another day offs, but a day off in the amusement part, it's a win. It's so funny how his thoughts seems to be condescending against his own actions. I liked how he's open with humanly things despite having a goal in eliminating humanity, such as exploring human-made entertainments and of course we never forget his favorite, PANDAS! I'd like to note his cuteness while riding that panda cart.
