[Another Castle]

Now I think we can all agree that Bloo has gotten naughtier as the series has gone on (he doesn't seem so destructive in House Of Bloos)- before he moved to Fosters, was he better behaved (if still hyper and wisecracking) ? I ask because he gets coal for Christmas (I've recently watched A Lost Claus for the first time). To Mac, this proves that Santa is real ("No one as naughty as you could have got nothing but coal!"). Or did he get coal every year before?
