Did you ever wonder what a shell keeps as a pet? What it uses for skis? How well it does in a fight? In this equally adorable and hilarious short, "Marcel the Shell with Shoes On," all your questions you never thought to ask will be answered. Directed by Dean Fleischer-Camp and voiced -- without enhancement -- by "Saturday Night Live" cast member Jenny Slate, Marcel will make you wish you had a tiny shell person hanging out in your apartment, using your nail clippings as skis.
