Moulding Mushroom

The is a type of mushroom that quickly spreads on the rationales of the ship during a night. The Sea Route of Silence Gang used the mushrooms to infect Konoha ship sailing towards the Land of Lightning.

At first, it looks like an edible ordinary mushroom, but after a night of spreading spores, new mushrooms are divert in colours. By eating the mushrooms, a person becomes purple in face, and mushrooms spread on their bodies also. Some 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 disappeared by getting out from the Sea Route of Silence, they received amnesia from what happened.
