When it comes to Mr. Poopybutthole, you really have all you need there.
Plus, imagine the publicity the series would get when people unfamiliar with Rick and Morty find out Adult Swim greenlit a show titled “Mr. Poopybutthole.”
A series could really just be like a slice-of-life comedy where he’s just going about his day-to-day, and that’s going to be enough for Rick and Morty fans to watch.
The outrage for this unbelievably wholesome character will be hilarious and make the spinoff that much more enjoyable.
