"The Scroll's Secret: No Peeking Allowed" (のぞき見厳禁!巻き物の秘密, Nozoki mi Genkin! Makimono no Himitsu) is episode 35 of the original Naruto anime.
In need of a second scroll, a recently awakened Naruto contemplated forging a new scroll, although he would first need to read the original one that they already had. Before he could do so, Kabuto arrived to stop him, citing that those who read the scroll were rendered unconscious until the exam's end; and that a rival team had tried to open their scroll and had suffered this fate. Kabuto, separated from his teammates, accompanied Team 7 to the tower at the centre of the forest. Along the way, the group encountered a disorienting genjutsu set by the teammates of the Ame genin that Sasuke had earlier defeated. By the time they realised that they were not getting any closer to the centre of the forest, it was too late, as they were attacked by a number of clones.
