Chapter 766, One Piece Wiki

Chapter 766 is called "Smile". As a tribute to Naruto's ending, Luffy eats ramen (Naruto's favorite food) with Chopper on his head and Nami as a waitress with a Konohagakure design changpao at a restaurant. A little fox eating ramen and wearing an Uzumaki sleeveless shirt is seen among them. There's another character sharing Luffy's table, eating meat (Luffy's favorite food) but it is covered by Nami so his face is unseen; however, due to his clothes and size it is heavily implied that it is Uzu
