"Eat or Die! Mushrooms from Hell" (食うか食われるか!踊るキノコ地獄, Kuu ka Kuwareru ka! Odoru Kinoko Jigoku) is episode 229 of the Naruto: Shippūden anime.
During their journey to the Land of Lightning, Naruto and the others stops at a nearby port to stock up on supplies and prepare to enter the Sea Route of Silence, 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, as well as devouring all of the food and water on the ship. After resisting for a long time without food, Naruto and Guy eat the mushrooms, but are poisoned and loose self-consciousness resulting in a skirmish between the two. As they regurgitate the mushrooms, Naruto summons Gamatatsu and has him ask Shima for some of her insect cooking.
The merchant and his gang infiltrate the ship, believing everyone to be dead. However, the Konoha shinobi defeat them and place them on a small boat, sending them back along the Sea Route of Silence with the moulding mushroom as their only source of food. As they exit the route themselves, Guy becomes seasick once more and Yamato recovers from his temporary illness.
