Fisch’s latest Glorp Alien update brings in a brand new NPC and a short questline to explore before the huge Fischmas event. While you wait for that, and check in every day to claim gifts from the Advent calendar, you can work on this quest and get the Gleebous mutation for the Dr Crookspine NPC. If you’re yet to find the place of fishing these up, check this guide below to find the exact fishing location for the Gleebous mutation in Fisch.
Where to Find Gleebeous Mutation in Fisch
The only place where you can get fish with the Gleebous mutation is at the waters near the Roslit Bay. The exact coordinates for fishing this mutation are: -1441.2, 133, 262.9, and you can use a GPS in Fisch to locate this easily. This means that the waters on both sides of the crashed UFO site have a chance of offering fish having that mutation.
Alternatively, you can also turn on the Fish Radar and check out this area. The region with an abundance of Gleebous mutated fishes will be shaded in light green, the same color as the UFO light. So, take out your best rod and start fishing here.

Do note that fishing in this area is the only way to get the Gleebous mutated fish, and you can’t get it from the Appraiser, so better to save your money and totems.
Best Rods to Catch Fish with Gleebous Mutation
Since the location to find the Gleebous mutated fishes is clear to you, it’s time to check what rods can help in catching them faster than anything. So, after testing them out and checking their stats, we have selected the following fishing rods are the best for catching them faster:
- Fabulous Rod: Perfect for endgame players with level 1000 and above and having completed all Fabulous Deity quests, this is a great choice. With 100% Lure, it will take a few minutes to get hold of the Gleebous mutation.
- Dreambreaker Rod: This one has 120% Lure, and with the extra progress speed boost, you can catch fish as soon as you throw the reel.
- Wind Elemental Rod: This rod has 555% Lure, and an additional 50% progress speed boost, which also helps in catching them fast.
