The Third Hokage taught the little Jiraiya to practice ninjutsus hard but Jiraiya said that using Perspective to peep at other people take shower is also a practice and the Third Hokage even showed great interest in this ninjutsu!
I like Naruto's anime and I believe it is one of the best anime ever. A lot of arcs of this anime touch the viewers' hearts; even now that the anime is over, I started to play Naruto Online, a Naruto game which closely follows the anime's original works with the same touching moments, similar design in ideas, sceneries, ninja and its amazing storyline! In “Naruto”, a “Kage” represents the strongest ninja, the zenith of power acknowledged by a village, the strongest of all Five Lands. However, in “Naruto” there is one ninja who killed two “Kage” and his power is feared by many – Orochimaru. The first biggest villain of “Naruto” was Orochimaru, even Kakashi, an Elite Jonin, feared his power. Orochimaru was originally a ninja from the village of Konoha, after his forbidden jutsu trials on real humans were found out by the Third Hokage, Orochimaru ran. Years later, the decision of the Third Hokage of letting Orochimaru go away without any consequences, brought Hiruzen his own death.
Orochimaru started a secret plan to invade Konoha, he used the Land of Wind after killing their Fourth Kazekage (Gaara's father). Later, he pretended to be the Fourth Kazekage and started the Chunin Exams in collaboration with Konoha, however, this was all a plan to overthrown Konoha. Konoha ended up in chaos and Orochimaru single-handedly fought the Third Hokage. Because most of the heroes of Konoha had been killed or were dead (White Fang of the Leaf, Minato Namikaze, Shisui Uchiha, among other) and because Tsunade was not in the village at that moment, the Third Hokage ended up fighting Orochimaru by himself online Naruto games. Due to his advanced age, his strength was no longer what it was before, even though he could still be a match by himself with Orochimaru. Later during their fight, Orochimaru used “Edo Tensei” to bring back the First Hokage and Second Hokage. At this point, the Third Hokage had to use much of his Chakra to fight off these two, he had to come up with the Reaper Death Seal Jutsu in order to stop the Hokage. Having lost control of the fight and seemingly defeated, he used hist last strength to seal away Orochimaru's two arms, making him unable to use hand seals to cast his precious jutsu.
