I almost forgot about this challenge until my friend ecnelisterger posted his and reminded me. I spent all but 5 minutes panicking over my lack of ideas when this popped into my head! To those who don't understand why there's so much blood; note the torn up and bloody ghost costume left on the ground. To sum it up: the frankenstein kid killed and ate the ghost kid, putting meaning into the statement "...Give me something GOOD to eat..."! (i know, lame)
To be honest I'm not completely satisfied with it, but I still like it. And I would've put in a second, humorous, entry for this but I just didn't have the time... So without further a due (spelled right?), I give you...my trick or treat challenge entry, I hope you like!!!
EDIT: Sorry about the fuzziness, it takes away like half the detail! *argh*
