Trick-or-Treaters on Parade

So here's my submission for the Halloween Fun Fest on starmen.net. Lolz, I'll give super-extra-awesome brownie points to anyone who can guess who Ness is supposed to be. Or who starman and Picky are suposed to be. Or who Poo and Paula are supposed to be (but Poo's is super-easy). Or who Tracy and King are supposed to be. Or who Jeff and Tony are supposed to be. Or...

Oh boy, this is so much fun!

EDIT: Alright, most of you wouldn't notice this, but I was messing around with the colors and such and I also resized it cuz my original was kinda blurry. So now it's brighter and easier to look at!
