You are lucky because with Halloween approaching, there are lots of ideas for monster treats online... I'd google search it for ideas (Sorry, I hate when I ask a question and someone tells me to google it), but my point is that there are lots of ideas out there right now, and although I can't point you in the direction of your specific question, you may find other equally as cool ideas... a specific site to look at is FamilyFun.com... they have some cute ideas... also, MarthaStewart.com... she does too.
Good luck finding some cool monster treat ideas!
