Formation! New Team Kakashi!

is episode 34 of the Naruto: Shippūden anime.

Synopsis
Unable to identify Sai, Naruto, Chōji and Shikamaru attempt to capture him, but Sai withdraws. Concerned that Akatsuki might soon come to Konoha looking for the Nine-Tailed Fox, the village elders of Konoha Council confront Tsunade. They propose that Tsunade keep Naruto in Konoha and not send him to missions outside the village. Tsunade declines, and promises to protect Konoha with her own life if Naruto is captured. However, she is still forced to compromise with Danzō by adding Sai as a new member to Team Kakashi. With Kakashi in the hospital, Tsunade temporarily replaces him with Anbu member Yamato and tells him to keep an eye on Sai. Later, Naruto and Sakura meet their new team members, and Naruto is immediately angered upon Sai's appearance.
