Volatile Gruzzer

"Gruzzer swollen with infection and primed to burst. Horrible goo and noxious gas has started leaking down from above. Is there a source of all this pestilence? If so, I haven't seen it."

Volatile Gruzzers are enemies in Hollow Knight. They are enlarged Gruzzers who still float around carelessly, their bodies swollen and dripping with Infection.

Behaviour and Tactics
Similarly to regular Gruzzers, they bounce around aimlessly in their territory, but they will now drip globs of harmful infection beneath them as they go. Avoid the drops by dashing and using the platforms as cover.

Once defeated their corpses will shake violently and then explode.

Location
Most of the Gruzzers become Volatile Gruzzers after the Infection consumes the Forgotten Crossroads, therefore their locations are similar. They can be found in the northwest of the Infected Crossroads. Volatile Gruzzers also appear in the Colosseum of Fools, in the Trial of the Conqueror during the fifth wave.
