Well if not Halloween, then maybe the next Friday the 13th. Or 06/06/06

Hmm... thats the only time I think that you could really symbolize it...

Unless you want to make some wacky new things for another season... ie. Christmas or Easter, New Years, etc...

lol new levels taking out posessed Santas and elves(could be D&D type elves instead) or killer bunnies...
