The Legendary Ino–Shika–Chō

is episode 239 of the Naruto: Shippūden anime.

Summary
As Team Asuma considers the impending war, they encounter Kosuke Maruboshi who reminds them of the time that they rescued him while they were still genin. With this, Kosuke retells the tale of the time their fathers saved him during the Invasion of Konoha with their Formation Ino–Shika–Chō. Somewhat rattled by this story, Kosuke reminds them that great shinobi weren't made in a day. As the team contemplates everything, they decide to perfect their own formation, insisting that they'd be fine because they were not alone.

Trivia

 * Both the Yamanaka and Akimichi clan's symbol shown in this episode are erroneously depicted compared to the symbol shown in the manga. The Yamanaka symbol has no lines touching the circle and the Akimichi's is noticeably missing the vertical line that is supposed to run through it.
 * In this episode, Shikaku is briefly shown without his goatee.
