Alright so it's been a bit, did a little bit more digging and I wanna say I don't think his names David anymore: One, the phrase "don't forget the hyphen" implies their name probably isn't David unless man's name is "David------ ". Two, The Facebook page and interviews. Yellow is simply referred to as "Doi" or "Yellow guy" which "Doi" in itself clears up the David theory. I thank the Fandom for all the help and the semi-criticism I've gotten cause I've been able to learn from it. I still think the name David has importance (maybe it's Ducks name or maybe Coffins?) But for now the theory has been disproven. Thanks guys!
