New Sexy Technique

In an omake included with the second Naruto fanbook, and later animated and shown after the credits of Naruto: Shippūden episode 188, Naruto uses his New Sexy Technique in order to get Jiraiya, who is concentrating on his new novel, to light the fire for their fish dinner. Excited by the technique, Jiraiya suggests Naruto wear a thong as part of his transformation in order to help Jiraiya come up with a female character for his novel. Confusing a thong for a mawashi, Naruto transforms into a sumo wrestler. When Jiraiya becomes angry with him, he uses the form to knock Jiraiya out. Naruto references this technique when he returns to Konoha after his training, resulting in him being punched to the distance by Sakura.
