Record of the Gutsy Ninja Master and Student

is episode 188 of the Naruto: Shippūden anime.

Summary
Naruto and Jiraiya become determined to free the village from under Kandachi's rule against Tanishi's will. They soon confront Kandachi who summons the Conch King on a lake. None of the Naruto's techniques work, because Kandachi's Conch King shell has a good defence and moderate offence. Meanwhile Tanishi is so afraid, he begs for Kandachi to let his mother and villagers go as Kandachi threatens to kill them. Naruto and Jiraiya free the villagers who hang above the water and Jiraiya moves off to take them to shore with the help of Tanishi. Naruto determinately fights Kandachi even though he keeps getting beaten down by the Conch King's tentacles. Jiraiya soon joins the fight and both Jiraiya and Naruto are caught in the Water Release Genjutsu: Mystic Fog Prison, but soon Tanishi uses Chilli Pepper Bombs to free them. In the end Naruto defeats the Conch King with the Great Ball Rasengan.
