Fisch Oliver Boulder Rescue Quest Oil Rig Guide, How to Find Them & Get All The Fish!

The Oil Rig questline continues with one of the most important steps: recruiting five workers by giving them specific items in Fisch. Each item works as a “bribe,” meaning you must collect the exact fish or object requested before the worker agrees to join the Demolition Crew. Some of these are simple catches. Others require correct weather, bait, or even special tools like Crab Cages. Below is the complete and precise breakdown of where to go and how to catch every required item.

1. Atlantean Captain’s Goldfish (Worker: Paul)

  • Location: Forsaken Shores
  • Exact Spot: Hidden pond at the back of the island
  • Best Conditions: Day / Summer
  • Best Bait: Truffle Worm

Head to Forsaken Shores and move toward the small, hidden pond behind the main area. Do not fish in the ocean — the Goldfish only spawns in that back pond.

Tips:

  • Fish during Daytime for better efficiency
  • Summer weather improves consistency
  • Bring Luck boosts if available

Since this is a Mythical-tier catch, expect some grinding.


2. Banana (Worker: Hayden)

  • Location: Ancient Isles
  • Exact Spot: Pond area (accessible by zipline)
  • Best Conditions: Rain / Summer
  • Best Bait: Weird Algae

Travel to Ancient Isles and use the zipline to reach the pond area. The Banana is a Secret rarity item, which means spawn rates are low.

Best strategy:

  • Wait for Rain or Summer weather
  • Use Weird Algae bait for increased odds
  • Stay patient — Secret-tier items can take time

Avoid switching spots too often. Consistency helps.


3. Sea Mine (Worker: Elias)

  • Location: Desolate Deep
  • Method Required: Crab Cages ONLY

Sea Mine cannot be caught using a fishing rod.

Steps:

  1. Travel to Desolate Deep
  2. Place multiple Crab Cages in deep water
  3. Wait and collect

Using multiple cages at once increases efficiency. High Luck boosts, such as Merlin’s Luck, can help speed up the process. Do not attempt normal fishing — it will not work for this item.


4. Pufferflute (Worker: Theo)

  • Location: Roslit Bay
  • Exact Spot: Coral Reef area
  • Best Condition: Summer
  • Best Bait: Seaweed

Go to Roslit Bay and fish in the Coral Reef section specifically. Pufferflute is Rare rarity, so this one is significantly easier than Banana or Goldfish.

Summer weather combined with Seaweed bait improves catch rate noticeably.


5. Rubber Ducky (Worker: Samuel)

  • Location: Vertigo
  • How to Reach: Enter a Whirlpool
  • Fishing Spot: Dark water area
  • Weather Bonus: Rain increases odds

To reach Vertigo, you must enter a Whirlpool somewhere in the ocean. Once inside Vertigo, fish in the darker water zones. No specific bait is required, but Rain weather improves efficiency. Rubber Ducky is not difficult, but reaching Vertigo is the main step players often forget.


The Oil Rig worker recruitment quest requires proper planning more than raw grinding. Each item has a specific location and ideal condition, and Sea Mine requires a completely different method using Crab Cages. Once you collect all five items and deliver them to their respective workers, you’ll successfully complete the Demolition Crew phase and move forward in the Boulder Rescue storyline.
