Flukemunga

"Aged fluke, grown fat on the rich refuse found in the pipes below the capital. When predators are too successful the surplus food they eat becomes soft bulk wrapped around their bodies. Still, these creatures at least seem to make good use of their additional weight."

Flukemungas are enemies in Hollow Knight. They are bloated Flukes who excrete a grease that helps them slide around the tunnels where they live.

Behaviour and Tactics
Wanders back and forth in a straight corridor. When it senses the Knight it will hurl itself towards them, dealing two masks of damage on contact and only stopping when hitting a wall with a jarring thud.

Flukemungas are found within small tight corridors and take little to no knockback from hits. Because of this and the fact that they have very high health, it is recommended to not engage Flukemungas but rather wait for them to pass by and then cross, treating them more like an obstacle.

Fragile Strength / Unbreakable Strength and Quick Slash are recommended to dispatch the Flukemunga before it can build up momentum. Using Shade Cloak or the invincibility from Desolate Dive is also an option to get behind it and out of its way.

Location
The Flukemungas can be found in Royal Waterways, to the east of the Junk Pit, making the way to the Godseeker much harder.

Trivia

 * The Flukemunga is one of three enemies added in content packs that are required for the Hunter's Mark, the other two being the Hive Knight and Pale Lurker.
 * Flukemunga was created when Team Cherry had to put a pitch together for Nintendo Treehouse 2018. They did not want to have the entire pitch only set in Godhome and therefore created a quick and easy enemy that would "really sell the new content pack".
