This seemed to be one of the longest episodes. I'm glad of that! It's great to make enough time to create as many good jokes as possible. We seem to be introduced to new characters. Yes, this was made about the same time Pluto was no longer considered a planet.
It's always great to look into the past. It still isn't a planet. It looks like the Moon itself can talk! I don't know if that's the relative size of the Moon to Pluto. I want to do my research.
