Gulka

"Aggressive plant-life that retracts protectively when danger is near. Spits hard spikey balls when foes are at a distance. Its leaves are dry and bland. The bud is unpleasantly sour, but oh! The venom in those balls it spits. Exquisite! If you have the time to spare, try drinking some and enjoy the effects."

Gulkas are enemies in Hollow Knight. They are plant-like beings who spit venom-filled spikey balls at intruders. The venom has certain enjoyable effects when it is consumed.

Behaviour and Tactics
Shoots spiked balls in the Knight's direction. These balls will arc very slightly with gravity.

When approached it retracts into the wall or ceiling it has grown on, making it hard to kill. To damage it, either increase the Nail's range with a charm such as Longnail, use a Nail Art such as Dash Slash, use a spell such as Vengeful Spirit, or reflect the spiky balls it spits back at it by striking them with the Nail.

Location
Found in large quantities in Greenpath, to the west of Stone Sanctuary.

Trivia

 * If the projectile it spits runs into a wall it will bounce about harmlessly for a few seconds before splitting open and disappearing.
 * The Gulka is one of the few enemies that respawn upon leaving and re-entering the room.
