Eat or Die! Mushrooms from Hell!.Naruto's ship stops at a port to resupply in preparation of heading into the Sea of Silence, a stretch of ocean with no wind or fish which takes two weeks to traverse. While buying supplies, Naruto purchases a mushroom called a Moldshroom from a merchant, which supposedly helps sailors avoid starvation. But once on the Sea of Silence, the Moldshroom multiplies quickly, destroying all of the food and water. Yamato falls into a coma due to the fungi eating away at his Wood Style chakra and starving painfully for days, Naruto and Guy eventually resort to trying the Moldshrooms. Poisoned and violently attacking one another, the blows cause both of them to expel out enough mushrooms from their system for a moment of sobriety. Out of options for food, Naruto summons Gamatatsu intending to eat the toad but instead has Gamatatsu bring back Shima's meal of insects for the crew to eat, enabling them to survive and ambush the merchant and his two associates when they attempt to rob them. Once out of the Sea of Silence, they send the criminals back along it with a Moldshroom. Naruto ends up being forced to choose the now inert Moldshrooms or Shima's cooking.
