In the rather dark Disney movie The Black Cauldron (1985), there is a fantastic creature named Gurgi who is perennially and insatiably hungry. Gurgi is omnivorous and prefers his food live. When searching for a nummie, he is wont to say ""Munchies and crunchies in here somewhere." My (parentally demented) children adopted this phrase, as well, and, if they were hungry, would demand "munchies and crunchies." This phase has, I think, passed.
