What about George? According to the modelsheet, he didn't even have a name at first (he was labelled "Moose").

Yeah, I do hope at least Maria becomes as interesting and prominent as they've managed to make George.  Something about her design already makes me like her.  Her tallness, soggy socks and cropped hairdo all come together wonderfully.  I really like the few shots of her with glasses, too. 

We've seen him jump off the bus steps roaring like a T-Rex in "Buster's Dino Dilemma". He had the second lowest score in the student-of-the-month chart in "MacFrensky". He has also demonstrated other trouble-maker qualities. He's also camera-shy.

I think there was also a scene of him throwing a paper ball at someone.  He seems to have his hands in his pockets a lot, too.

I could picture him being a practical joker whose pranks maybe go too far sometimes.  Someone who likes to set people up for humiliation, then stand aside in the shadows and laugh at them without them ever figuring out he had anything to do with it. 

I think the show could use a new villain, now that the Tough Customers are not-so-tough and Molly has been mollified.
