Mycellium looked upon the writhing serpentine mass of plant matter with an empty stare. It felt nothing about this creature, that once it might have called brethren. It might have attempted to reason and make peace, Deku to Deku. but  Mycellium, if he had ever had a conscience or mind of his own, was now only an extension of the fungus. A relatively advanced extension in comparison to the typical shambling mushroom monster, but no less a part of a parasitic mass, and not a thinking individual.

The Kokiri beast was lobbing bombs, attempting to extract some sort of vengeance on the creature. The fungus creature did not have such a motive, but it did have patience. And so it waited for the perfect time to strike.
