Since nobody else wants to give you serious recommendations, perhaps grinding up some Oreos and mixing them with gummi worms and a little milk. Or you can just use dirt from the backyard (and a little water if it's too dry), since that would mean smashing a lot of Oreos, and you wouldn't be able to eat the mixture in the end anyway because where those kids' hands have been is anyone guess.
Where are these lemmings going? The
