Hwurmp

Tiny and placid but swells to enormous size when threatened. Extremely amusing creature.

Hwurmps are enemies in Hollow Knight. They are tiny creatures who have powerful, expandable lungs which allow them to swell up to an enormous size.^[1]

Behaviour and Tactics

Floats around passively until the Knight approaches them, after which it will slowly float towards them. Upon taking damage or colliding with an enemy or the Knight, it will inflate and bounce off objects, walls and water surfaces. After a relatively short period, they will revert to their original form. If they inflate inside a tight space where their inflated body cannot fit, they will instantly die.

Be careful when dealing with them in bigger numbers as they inflate each other upon contact and groups of them can easily fill up a room quickly.
