The Scroll's Secret: No Peeking Allowed

is episode 35 episode of the original Naruto anime.

Synopsis
In need of a second scroll, an awakened Naruto contemplates forging a new scroll, though he'll first need to read the scroll he already has. Before he does so, Kabuto arrives to stop him, citing that those who read the scroll are rendered unconscious until the exam's end; a rival team tries to open their scroll, and suffers this fate. Kabuto, separated from his teammates, accompanies Team 7 to the tower at the center of the forest. Along the way, the group encounters a disorienting genjutsu set by the teammates of the Rain Genin that Sasuke had earlier defeated. By the time they realize that they are not getting any closer to the center of the forest, it is too late; they are attacked by a number of clones.
