A new update has arrived in the popular game Fisch. It introduces a fresh NPC and a short questline. Players can explore this content now before the major Fischmas event begins.
The update centers on obtaining a specific fish mutation. This mutation is required to progress a new character’s story. According to developer notes, it is a limited-time opportunity tied to seasonal events.

Exclusive Fishing Location for the Mutation
The Gleebous mutation can only be caught in one specific area. Players must fish in the waters near Roslit Bay. The precise coordinates are -1441.2, 133, 262.9.
This location is directly adjacent to the game’s crashed UFO site. Using the in-game GPS will help players navigate there quickly. The area is marked by a distinct green hue on the Fish Radar.
Fishing here is the only method to obtain this resource. It cannot be bought from the Appraiser NPC. This makes the activity essential for quest completion.
Optimal Gear for a Successful Catch
Using the right fishing rod drastically improves success rates. High-lure rods are particularly effective. They reduce the time needed to hook a mutated fish.
The Fabulous Rod is a top-tier choice for high-level players. It offers a 100% Lure stat. The Dreambreaker Rod is another excellent option with 120% Lure.
For the fastest results, the Wind Elemental Rod is unmatched. It boasts a massive 555% Lure stat. This rod significantly speeds up the fishing progress bar.
Completing the Gleebous mutation hunt is a crucial step. It directly unlocks further dialogue and rewards with Dr. Crookspine. Players should focus on this activity to fully experience the latest Fisch update.
