Fungoon

Fungoons are enemies in Hollow Knight. The adult form of the Funglings, these fungal balloon creatures attack by spitting streams of noxious gas.

Behaviour and Tactics
Floats around in the air until disturbed. It blows a blast of infected gas at its foe from above. This blast is fairly slow and easy to dodge. The Fungoon can only release this gas straight down, making attacking from above the best option.

Location
They can only be found in most of Fungal Wastes, except for the Mantis Village.

Trivia

 * Upon being defeated, it will deflate like a balloon, squeaking noisily.
