Eat or Die! Mushrooms from Hell

is episode 229 of the Naruto: Shippūden anime.

Summary
The group stops for 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 from Naruto begins to multiply and to absorb the chakra of Yamato. After resisting for a long time without food, Naruto and Guy tasting mushrooms poison them and push them to act in a violent manner. Without alternatives, Naruto calls Gamatatsu and asks him bringing him Shima's food, composed on insects. All aboard eat and regain strength, even managing to defeat the pirates who sold them the mushroom when they come to look for valuable cargo.
