When your poopoo is an unusual color, it's important to let everyone know about it.

As far as I know, green is no reason for alarm as long as you have a reasonable guess as to its source. And it's not animals-to-ninjas green, or if-it-bleeds-we-can-kill-it green.

Writing comedy involves many subtleties that likely go unappreciated by casual audiences. The writer is constantly making seemingly minor word choices that could, in fact, make or break the flow of a joke. Do you call it "poo", "poop", "poopoo", "doodoo", "dookie" or even "doots"? Take the comedic shortcut of throwing in profanity? For this strip it amused me to imagine a "poop" as one of many distinct entities. One in a collection or, if you prefer, a series.
