The "Naruto: The Lost Story - Mission: Protect the Waterfall Village" special has parts where it focused on accidentally stepping on doggie poo whilst the movie "Doggy Poo" has a piece of doggie poo as the main character.
It is interesting to see doggie poo portrayed in various ways in different media. It is a good idea to get the whole spectrum of what doggie can be, not just for individuals, but also for society.
I know this may sound insane, but they are similar.
Both anime attempt to make a change in the watcher, or to teach you something. They have different animation types. They are both also great stories!
