The Forest of Chakra - S1.E3

Brought to Tazuna's home to recover from his fight with Zabuza, Naruto meets the bridge builder's grandson Inari, while Kakashi awakens realizing that there were numerous inconsistencies between the actions of the masked youth and that of other hunter-nin. Expecting to face Zabuza again, Kakashi decides to take Team 7 to the woods to teach them chakra control by having them walk up a tree by focusing chakra beneath their feet.
