Ooh, I just saw something clever earlier today, too. I shall go find it!
edit:
I'm probably not actually going to wind up doing this, but I did get invited to a kid-party & they're asking for us to bring spooky snacks but go "light on the sugar" if possible. Tall order!
I thought these dipped strawberry ghosts were a cute idea ~

Also, neat salad presentation, though eating it might be messy:
I'll have to keep looking for other festive things with an element of 'something healthy in there somewhere' to them. :)
