Senjutsu

refers to the user's chakra created from spiritual and physical energy within the shinobi as well as energy from nature. This drastically increases the strength of all physical attacks and jutsu. It would seem that it stems from the toads, as only Jiraiya and Fukasaku have been shown using them, and Gamakichi being the only one who is familiar with it. Other than Jiraiya, Naruto Uzumaki, who also possesses a large chakra reserve that enables the production of high amounts of chakra is the only other human capable of learning and using Senjutsu. Unfortunately, if the user puts too little natural energy into using hermit techniques, the technique will not initiate and if the user puts too much natural energy into the techniques, the user will start to turn into a frog. If a special scepter is not in contact during the transformation by a toad, the user will completely transform into a frog. Jiraiya, a legendary Sannin, had trouble using his sage form and he slightly turns into a frog. This involved his nose and hands and face changing to a more toad-like appearance. However, Naruto, who has just learned how to sense natural energy and create sage chakra using the Secret Toad's Oil, only has dark rings around his eyes and horizontal, slit-pupils showing better control. He is still able to use his sage chakra well, since he was able to lift a giant frog statue with his sage chakra but accidentally drops it prompting Pa to remark that Naruto is even clumsier then Jiraiya...
