Danger! Sage Mode Limit Reached

is episode 164 of the Naruto Shippūden anime.

Synopsis
The improved Wind Release: Rasenshuriken was avoided by three Paths of Pain, while the Human Path was vaporized. The Animal Path engaged Naruto (who was running out of senjutsu chakra). Through a diversionary tactic devised by Shima, Fukasaku and Gamabunta, it was incapacitated by Sage Technique: Rasenrengan. The Deva Path then tried to assault Naruto, which was turned to its disadvantage when Fukasaku reversed-summoned one of Naruto's shadow clone that was collecting Nature Energy in Mount Myōboku, restoring Naruto into Sage Mode. When Naruto attempted to finish the Deva Path with another Rasenshuriken, the Preta Path immediately jumped to absorb it, having been repaired by the Outer Path. With this setback, Naruto devised a three-step diversionary tactic to permanently disable the Naraka Path. With Deva Path regaining its power, he used Shinra Tensei to repel Naruto and send Gamabunta, Gamaken and Gamahiro flying beyond Konohagakure's borders.

Omake
Katsuyu feared that with Manda deceased, Gamabunta and the toads of Mount Myōboku would now try eating her.
