Fisch Caustic Hallow is the Halloween island for the FischFright 3 event in Roblox Fisch. Reach it by boarding the green-lit Flying Dutchman at Moosewood’s eastern dock and speaking to the captain. You’ll arrive beside a village fountain, where paths lead to the Scarecrow Maze, Witch’s Cauldron, Haunted Mansion and Cemetery.
The main reason to explore Fisch Caustic Hallow thoroughly is that its NPC quests overlap. The Witch and Youngster Goblin both need ingredients, Pumpkin Pete and Dullahan award ritual roses, and several of the quests count fish you catch for others. This guide walks through all the major quest givers, six Haunted Mansion residents, merchants and the island’s important landmarks.
How to get to Fisch Caustic Hallow from Moosewood
Travel to Moosewood and follow the eastern beach towards the ghostly green ship. Board the Flying Dutchman, locate the Dutchman Captain marked as an Event NPC and choose to set sail. The travel sequence takes you directly to Caustic Hallow; you do not need to finish an unrelated quest to unlock the island. ‘Caustic Hollow’ is a common alternate spelling in some guides, but the 2026 destination is the same.
Once you reach Fisch Caustic Hallow, use the central fountain as your reference point. Signposts point to the Fountain, Graveyard, Cornmaze and Bat Cave. The numbered houses let you trick-or-treat with the Candy Bucket, and the Halloween Quest Book tracks each major questline. Start the Pumpkin King’s tasks before your first fishing trip because later objectives take you back to the main islands.

Fisch Caustic Hallow fountain and Pumpkin King
The Pumpkin King is close to the village fountain. His quests begin with fifteen event fish and continue through Witch’s Ingredients and five Spooky Markers. Those markers belong at docks on Moosewood, Roslit Bay, Snowcap Island, Castaway Cliffs and Forsaken Shores. Pick up the quest before you leave Caustic Hallow for goblin challenges, otherwise you may need a second trip to the same islands.
The Fisch Caustic Hallow village contains sixteen decorated houses. Equip your Candy Bucket to knock on their numbered doors, earn Treats and occasionally obtain special candy fish. Visiting sixteen distinct houses is also a Webby Winston objective, so start his quest before doing a full door circuit. The current Fisch codes page also lists codes that can help with event rewards.
Fisch Caustic Hallow Witch’s Cauldron and Youngster Goblin
Beatrix waits by the cauldron near the central tree. Goblin challenges across the main sea provide Witch’s Ingredients, which she converts into Hex Energy for rod and cosmetic milestones. Nearby, the Youngster Goblin requires three Normal-or-harder goblin completions, ten ingredients, and the Boglin Skull, Twig and Wraps. Hand over his ten ingredients before using Beatrix’s Offer All Ingredients option or you may need to farm another set. Our Boglin Branch guide covers all three rare parts.
The Goblin challenges for Fisch Caustic Hallow take place on the regular map. Server messages announce spawns on thirteen islands such as Moosewood, Roslit, Snowcap, Sunstone, Terrapin, Ancient Isle, Forsaken Shores, Castaway Cliffs, Mushgrove, Scoria Reach, Lost Jungle, Skycrest and Everturn Forest. The objective can involve a fish, an emote, a chat command or trivia, so you can often clear a challenge without using any special rod.
Where to find Webby Winston and Doomsekkar
On Fisch Caustic Hallow, Webby Winston is inside the Webridden Cavern at approximately GPS -15069, 142, -9981. Follow the right-hand path from the fountain towards the cave. He asks for sixteen distinct house knocks, fifteen Cobweb Cod and ten Webbed fish caught inside the cavern. Completing the objectives reveals a rod you can buy for 1,000 Treats. The Webweaver Rod walkthrough includes the cave tasks.
Doomsekkar is behind and to the right of the Witch’s house, across the acidic river. His tasks require a hundred fish from active Frightful Pools, fifty consecutive perfect catches in those pools and a successful haunted-house ghost minigame. The reward is the Doomsekkar Rod and Treats. Refer to the Doomsekkar quest guide for the detailed perfect-catch objective.
Fisch Caustic Hallow Scarecrow Maze: all seven Scarecrows
The Gatekeeper Scarecrow is near GPS -14966, 181, -9430, in the hedge maze on the left of the island. Six other Scarecrows hold the actual quests: provide a Crypt Crab, retrieve a missing Straw Arm, perform an emote for fifteen seconds, give five Treats, catch a Decayed Dace and catch a Scarecrow Snapper. The Gatekeeper himself is the seventh Scarecrow and does not count as one of those six tasks.
The six quest NPCs are reported near -14951, 181, -9404; -14929, 181, -9346; -15047, 181, -9427; -15021, 181, -9442; -15066, 181, -9403; and -15050, 182, -9552. Return to the Gatekeeper after finishing them for access to the secret vault, including fifteen Frightful Caskets, 1,000 Treats, a Vile Relic and a Doomed Skull.
Fisch Caustic Hallow Haunted Mansion: Dullahan and six residents
At the hilltop mansion, talk to Dullahan and then enter the house. You must complete six residents’ requests, retrieve a family heirloom from an upstairs bedroom and bring Dullahan a Dobhar. Here is the resident checklist.
| Resident | What to bring |
|---|---|
| Butler Bartholomew | 5 Cobweb Cod |
| Chef Ghoulash | 3 Franken-Flounder and 3 Gargoyle Grouper |
| Maid Marrow | 8 Decayed Dace |
| Lady Lenore | 1 Shiny Headless Halibut |
| Portrait of Percival | 3 Haunted Haddock and 1 Jack-o-Angler |
| Nanny Nocturne | 15 event fish |
Dullahan awards Fable Rose, 3,000 Treats and XP. Fable Rose is one of the items used to awaken Cemetery Skeleton Hands, so retain it after the turn-in. Our FischFright 3 Ritual Roses guide explains where the other flowers come from.
Fisch Caustic Hallow Pumpkin Pete and Frankenstein
Pumpkin Pete is beside the Pumpkin Patch houses at about GPS -14727, 148, -10009. His four objectives are five trick-or-treat visits, five candy-type fish from doors, a Jack-o-Angler and five Treats paid to each of four nearby lanterns. You receive Gourdemort’s Rose and 2,500 Treats. These door visits also make progress towards Winston’s quest if you accepted it already.
Frankenstein stands at the Cemetery ritual circle, around GPS -15104, 146, -9621. Each attempt costs 100 Treats and uses specified offerings in pumpkins and sometimes Skeleton Hands. The eleven rituals eventually unlock Dutchman’s Rod, Omniscient Spinecaster and rare encounters. The complete ritual recipes give the exact ingredients and mutations needed for each one.
Fisch Caustic Hallow merchants, Rave and Witch Kitty
The island’s Frightful Merchant buys spare event fish for Treats, while a merchant aboard the flying ghost ship sells Davy’s Rose, Dutchman’s Grasp, Omniscient Souls, totems, masks and cosmetics. Dave’s Rave skin quest is up by the brightly lit disco ball on a mountain. Witch Kitty can spawn by the church, behind the mansion or near the disco-ball cliff. You do not need Witch Kitty to finish the main rod quests.
For the most efficient Fisch Caustic Hallow route, collect the Pumpkin King and witch quests first, then cover the village houses, Webridden Cavern, Pumpkin Pete, Scarecrow Maze and Mansion before heading to Frankenstein. Work on Doomsekkar whenever a Frightful Pool appears, rather than waiting until the end. The FischFright 3 event guide has the wider event schedule.
