It's going to be difficult to top this one. This is Andrew Bell's submission to the Crazy 4 Cult: Customs show. It uses one of his DIY O-No Sushi vinyl figures as the base, with some excellent sculpting and painting work.
And, of course, as if you didn't know...it's Sloth from The Goonies. He even has a tiny Baby Ruth in his back pocket. How about a Mama Fratelli, Andrew?
