The theme tune for Rick and Morty has existed longer than you'd think. This storyboarded pilot, uploaded to Vimeo in 2012, was originally going to use that song and was Justin Roiland's first attempt at making a show for Adult Swim, but he was so busy with other ideas of his that he just had to shelf it. The story of this is kinda like that skit in Road to the Multiverse, only Dog World is more than just furries treating humans as pets, and three children, one of being underdeveloped according to the creator, have to put up with living on this acid trip of a planet.
