Lekaraté de Foie Gras (必殺！ グルメ・デ・フォワグラ Hissatsu! Gurume de fowagura?) is the 168th chapter of the manga and the fourth chapter of the Martial Arts Dining Arc. The Tendos raid Happosai's collection of scrolls showing various martial arts secret techniques and come across a book discussing Cuisine-Fu. All of the masters are shown with giant mouths except for one man named "Le Petit Bouche". Le Petit Bouche developed a technique called "Le Parlay du Foie Gras", but the pages in the book describing the technique are missing.
