The Forest of Chakra

is episode 10 of the original Naruto anime.

Synopsis
Kakashi wakes rested and recovered at Tazuna's home. There, he made the observation that Zabuza's death had been odd, and concluded that it had been an act. Elsewhere, Haku revived Zabuza, who promised to crush Kakashi when next they met. Both Kakashi and Zabuza needed to rest a week to recover. With Zabuza's return a likely outcome, Kakashi took Team 7 to the nearby woods for chakra training, where they learned to walk up vertical surfaces. Sakura performed this perfectly the first time, but Naruto and Sasuke required extra training. Naruto asked Sakura for advice, and Sakura agreed to help him. Kakashi commented that Naruto was finally getting a good grasp on teamwork.
