The Webbed Mutation in Fisch is a limited FischFright 3 event mutation found in the Webridden Cavern on Caustic Hallow. To get it, sail over on the Flying Dutchman, fish the toxic green pool beside Webby Winston’s cave for 10 Webbed fish, then finish his quest β 16 trick-or-treat houses plus 15 Cobweb Cod β to unlock the Webweaver Rod, whose spider passive guarantees Webbed catches. Every step is tested.

Webby Winston guards the web-covered entrance of the Webridden Cavern on Caustic Hallow, the FischFright 3 Halloween island. I took the Flying Dutchman docked on Moosewood’s east side and asked the Dutchman Captain to set sail. After landing, follow the pumpkin-lined village path up to the glowing green cave at coordinates -15069, 142, -9981. Can’t spot the fishing zone? A Fish Radar instantly marks the Webbed pool.
Webby’s quest, FischFright 2026: Webby Winston, has three objectives β here’s how I cleared each.
Equip your Candy Bucket and knock on every numbered house in the Caustic Hallow village β one visit per door. The Quest Book tracks your progress, so follow its checklist instead of memorizing house numbers; the lists online don’t even match each other. Watch out for haunted homes like House 745, which triggers a “Catch the Ghost!” mini-game β when a door feels suspicious, pick Trick and move on.
Cast into the toxic green water inside the Webridden Cavern. Here’s where most players slip up: Webbed fish caught anywhere else don’t count β the mutation must roll inside the cavern pool. I kept my regular rod and enchantment untouched; no Enchant Relics or rerolled setup needed. Just cycle catches until the counter hits 10; Webbed fish sell for extra Sheckles.
The same green pool spawns Cobweb Cod, so this objective grinds itself while you hunt Webbed fish β that double-dip is the real time-saver. I swapped to Black Licorice or Candy Corn Cluster bait for faster Cod bites, banked all 15, then handed the batch to Webby Winston.
Turning everything in rewards 1,000 Treats and 8,000 XP, and the silk wall dissolves to reveal the Webweaver Rod pedestal. Buy it for 1,000 Treats β your reward nearly covers the price.

The passive is why this rod is worth the grind: three spiders follow you (without occupying your companion slot), and every catch gets a chance at the Webbed mutation. Stand on the web they spin at your feet and the roll becomes guaranteed. See how it compares in our Fisch Rod Tier List, or tackle another quest-locked rod with our Castbound Rod guide.
Only in the Webridden Cavern’s green pool on Caustic Hallow β Webbed catches elsewhere won’t progress the quest.
It’s a limited FischFright 3 mutation that multiplies a fish’s sell value. One mutation applies per fish, but Shiny and Sparkling attributes stack on top.
Finish Webby Winston’s quest, then buy the rod for 1,000 Treats in the newly opened inner passage.
Yes β the cavern pool is fishable from the start. The quest only gates the inner room and the rod purchase.
