Jenny Slate and her husband, Dean Fleischer-Camp, have graced the world with a third installment of Marcel the Shell With Shoes On, and it's absolutely hysterical. This time, Marcel laments his plant allergy, takes a dig at shrimp — "the idiots of the sea" — and reveals the "hot zone" where he needs to apply deodorant. It's the latest in a series of big moments for the character, who's voiced by Jenny. The book Marcel the Shell: The Most Surprised I've Ever Been [1] by Jenny and Dean comes out this week, and last week, Jenny talked about the origin of Marcel [2] with David Letterman [3], singing a silly song as Marcel.
