Hidden within Roblox Fisch lies one of its rarest secrets – the Gleebous mutation. To reel it in, players must master the right fishing rod setup, understand mutation triggers, and time their catches perfectly to increase their odds.
Where to Find Gleebeous Mutation in Fisch
Gleebous Mutation fish only spawn in the waters around Roslit Bay, specifically near the crashed UFO site at coordinates -1441.2, 133, 262.9. Use the in-game GPS to pinpoint this spot, then cast your line anywhere along the shoreline on either side of the crash, as the entire area shares the same mutation pool. Activating Fish Radar helps a lot here, since Gleebous-rich spots appear as light green zones matching the UFO’s glow, letting you stay inside the correct region while you fish.
Gleebous mutation is important to get the Blade of Glorp rod 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
Rods with high rarity bonuses and strong durability are the best for catching fish that can develop the Gleebous mutation. The Abyssal Rod and Crystalweave Rod offer the best balance between strength and mutation chance, making them reliable for extended fishing sessions. Upgrading your rod with gleam or mutation boosts increases the likelihood of attracting Gleebous variants, especially in deepwater zones where rare spawns are more common.
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.
Best rods to maximize Gleebous mutation chances
Blade of Glorp stands out as the top rod for maximizing Gleebous mutation chances in Roblox Fisch due to its significant mutation boost and high luck stats. Pair it with the Mutated enchant on any compatible rod to further increase mutation rolls while fishing at the Roslit Bay UFO crash site.
Top Rod Recommendations
These rods excel for Gleebous farming thanks to high lure speeds (for frequent casts) and progress boosts (for quick resolves), allowing more mutation attempts per session.
| Rod | Key Stats for Gleebous | Best For |
|---|---|---|
| Blade of Glorp | High luck + mutation chance boost | Dedicated Gleebous grind |
| Wind Elemental Rod | 555% Lure + 50% progress speed | Fastest cast cycling |
| Dreambreaker Rod | 120% Lure + progress speed boost | Balanced high-level play |
| Fabulous Rod | 100% Lure | Endgame players (level 1000+) |
Optimization Tips
Apply the Mutated enchant first-acquire relics from Merlin, then enchant any mid-to-high-tier rod for reliable results without needing endgame gear. Avoid rods with conflicting passives; focus on the Roslit Bay coordinates (-1441.2, 133, 262.9) and enable Fish Radar for mutation pools. High-luck setups cut grind time dramatically, with players reporting success in far fewer casts.
Which rod enchantments boost mutation rate most
Cursed I provides the highest direct mutation boost at +75% mutation chance, making it the top enchantment for maximizing mutation rates despite its -75% luck penalty. Mutation Hunter II offers a strong +30% mutation increase without drawbacks, ideal for balanced setups.
Enchantment Tier List
| Enchantment | Mutation Boost | Drawbacks | Pull Chance |
|---|---|---|---|
| Cursed I | +75% | -75% luck | 5% |
| Mutation Hunter II | +30% | None | 5% |
| Mutation Hunter I | +10% | None | 10% |
| Mutated (Fisch) | Slight boost | Varies by rod | N/A |
Application Strategy
Prioritize Cursed I on high base-luck rods like Blade of Glorp to offset the luck penalty while farming Gleebous at Roslit Bay. Combine Mutation Hunter II with lure-speed enchants for sustained grinding, as seen in Fisch community tests. Acquire via Enchant Stones at Esoteric Depths or evolved stones for rarer rolls.
