Fluke Larva

Fluke Larvae are tiny, immobile Flukes that line the floor and ceiling of certain rooms in the Royal Waterways. Although not having their own Hunter's Journal entry and thus not being official enemies, they nearly exactly resemble the nature of Maskflies - save for the ability to move.

Besides the tunnel leading to Flukemarm, they can be found in the tunnels with Flukemungas. More are scattered in Fluke Hermit's room, though they cannot be harmed. Fluke Hermit also refers to the larvae as "Little Sisters".

Like Maskflies, they do not deal contact damage and are generally harmless. They cannot be Dream Nailed but do give SOUL when killed - this makes them very handy sources of SOUL, as they are easy to kill and found in massive clusters. Their quantity also makes them very effective for grinding Essence as, like a normal enemy, they have a chance to drop Essence.

Trivia
 * The Fluke Larva's name is mentioned in the Wanderer's Journal.
 * In Fluke Hermit's secret room, the larvae cannot be killed.
 * Fluke Larvae respawn upon leaving and re-entering the room.
