The protagonist maintains a solitary and bizarre lifestyle, communicating through elaborate song while surrounded by odd inventions, a sizable Howitzer, and generally seeming rather eccentric. He habitually disregards his doorbell, but eventually feels compelled to answer it, leading into a strange sequence where his head is separated from his body and ricochets around the room attempting to return. I must admit, this didn’t entirely click with me; however, there's no denying an immense amount of inventive flair coming from someone whose thought processes seem completely alien to my own! "I roll yet I still sing"! Perhaps a simple fix would be disconnecting that doorbell?
