One Piece Odyssey Helping Iceberg 3 is the final side quest you will receive from the busy mayor of Water Seven City, Mr. Iceberg.
For the Helping Iceberg 3 side story, you’ll have to find out why people are getting hurt near the sewer and deal with the problem.
So, follow this in-depth guide if you wish to complete the Helping Iceberg 3 side quest in One Piece Odyssey.
How To Start Helping Iceberg 3 Side Story In One Piece Odyssey
As usual, you’ll find Mayor Iceberg in the northern part of the Water Seven City Area, still surrounded by NPCs complaining. You can check the map below for NPC’s location.

To begin the Helping Iceberg 3 quest, you’ll have to complete Helping Iceberg 1 we’ve covered here, then Helping Iceberg 2 (covered in-depth here).
After you’ve finished the two previous Iceberg quests, talk to him again to begin the final side story.
Where To Ask Around The Sewers In One Piece Odyssey
Mayor Iceberg is worried about the people getting hurt near the sewer and wants you to investigate by asking the people around the Sewage Treatment Plant.
Head to the southwest corner of the Water Seven City Area and talk to the three NPCs with a blue icon marker above their head in front of the sewer.
Take a look at the map below to learn the exact location.

After you finish the conversation with the tiny old woman, the big guy with a mustache, and Torva by the end of the stairs, your next objective is to defeat three Wild Golden Bats in the Sewers.
Enter the Sewers behind Torva, and let’s see where we can find 3 Wild Golden Bats in One Piece Odyssey.
Wild Golden Bat Location 1: South Of The Save Point
Once inside the sewers, take the Yagara to get to the other side, then follow the path until you see the Yoisa Travel sign on the left and the Save Point on the right.
Look directly south from the Save Point location to find the first Wild Golden Bat location.

You have the option to go and find the other two locations we’ve listed below, or you can fast-travel to the Sewer Entrance Yoisa Travel sign to make the Wild Golden Bat respawn.
Wild Golden Bat Location 2: Near The Elevator
The second Wild Golden Bat is located near the elevator in the southeast corner of the Sewer’s first level.
You’ll find the Wild Golden Bat in the hallway to the right, just before the elevator.

Wild Golden Bat Location 3: Southwest Corner Of The Sewer’s Second Level
For the third Wild Golden Bat location, take the elevator to the basement level two and make your way to the bottom left corner of the map.
The Wild Golden Bat is in a small room with a Treasure Locked Chest.

After you defeat three Wild Golden Bats, head outside the sewers and speak again with Torva, which is the NPC standing at the bottom of the stairs in front of the sewer.
Then, go back to the Mayor Iceberg location and report to him to complete the Helping Iceberg 3 side story and receive the following rewards:
- Iceberg’s Gift
- 59,000 Berries
