This whole series is a satirical joke.The cruddy art style, Synthetic Voice Actors, logo-centric humor and peculiar behaviors of main "creator" Robby are all just a joke. The entire Greeny Phatom franchise is, in fact, a massive satire on why parents shouldn't let their kids be on the internet. Think about it; the creator was presumably in his teens when the series began, and right now he's possibly in his twenties. Perhaps distraught by how people perceive the behaviors of little kids on the internet, he sought out to create this as a massive parody of those kids.
At least, we hope that is the case.
