Moulding Mushroom

The Moulding Mushroom is a type of mushroom that quickly spreads on a ship's rations during the night. The Sea Route of Silence Gang used the mushrooms to infect the Konoha ship sailing toward the Land of Lightning.

At first, it looks like an edible ordinary mushroom, but after a night of spreading spores, new mushrooms grow in different colours. By eating the mushrooms, a person develops a purple face and mushrooms spread on their bodies. Some of the mushrooms devour chakra like in Yamato's case. When people eat them, they become unaware of their own actions like in the cases of Naruto and Guy. After the mushrooms' effect disappears by getting out from the Sea Route of Silence, those who have eaten the mushrooms will forget what had happened.
