Eat or Die! Mushrooms from Hell

is episode 229 of the Naruto: Shippūden anime.

Summary
The group stops at a nearby port to stock up on supplies and prepare to enter an area devoid of fish of the sea and wind that takes two weeks to be crossed. In the hold, a mushroom purchased by Naruto from a vegetable merchant begins to multiply and to absorb the chakra of Yamato. After resisting for a long time without food, Naruto and Guy taste the mushrooms, but they poison them and push them to act in a violent manner. Without alternatives, Naruto calls Gamatatsu and asks him to bring him Shima's food, composed of insects. All aboard eat and regain strength, even managing to defeat the pirates when they come to look for valuable cargo.
