One of the side quests many players overlook in Sailor Piece is the Slime Key Crafter quest, which requires you to collect seven hidden slime pieces scattered across different islands. At first, the quest sounds simple, but the pieces are placed in specific locations across the map, and the order of islands doesn’t follow the normal difficulty progression.
If you’re trying to complete the quest quickly, this guide walks through every slime piece location step-by-step so you can collect them without wasting time searching.
All 7 Slime Piece Locations in Sailor Piece
Before you can begin collecting the slime pieces, you need to start the quest.
Head to Slime Island and speak with the Slime Key Crafter NPC.
The quest description will tell you to:
- Find 7 slime pieces across the map
- Collect them in order
Once the quest begins, you can start traveling to the different islands where the pieces are hidden.
Slime Piece Location #1 — Desert Island
Your first destination is Desert Island.
When you arrive, move toward the area underneath the structures on the island. The slime piece is hidden in a small spot under the terrain area.
You should see a glowing slime object sitting there. Interact with it to collect Slime Piece #1.
Slime Piece Location #2 — Snow Island
Next, travel to Snow Island.
Once you reach the island, look for a tree area nearby. The second slime piece is hidden behind one of the trees, making it easy to miss if you run past too quickly.
Walk behind the tree and collect Slime Piece #2.
vSlime Piece Location #3 — Starter Island
Now return to the Starter Island.
Even though it’s the beginner area, one of the slime pieces is hidden there. Move around the island until you reach another tree location, where the third piece is placed nearby.
Interact with it to obtain Slime Piece #3.
Slime Piece Location #4 — Jungle Island
Your next stop is Jungle Island.
Climb around the terrain and elevated areas until you reach a spot where the slime piece is placed on the ground near the jungle structures.
Once you interact with it, you’ll obtain Slime Piece #4.
At this point, you should have four out of seven pieces.
Slime Piece Location #5 — Shabondy Station
After leaving Jungle Island, travel to Shabondy Station.
Move through the lower part of the map and explore the pathways until you find the slime piece sitting in one of the open areas along the route.
Collect it to obtain Slime Piece #5.
Slime Piece Location #6 — Hueco Mundo Area
The sixth piece is located in the Hueco Mundo area.
When you arrive, move toward the section that contains two chimney-like structures. The slime piece is hidden between those structures, making it fairly easy to spot once you know where to look.
Interact with it to pick up Slime Piece #6.
Slime Piece Location #7 — Final Island Location
The final slime piece is located on another island further along the map.
After reaching the island, move forward through the area until you find a large tree. Look closely around the tree, and you’ll see the last slime piece sitting nearby.
Collecting it will give you Slime Piece #7 and complete the quest requirement.
Completing the Quest
Once all seven slime pieces are collected, return to the Slime Key Crafter NPC on Slime Island.
Turning in the pieces will complete the quest and reward you accordingly.
The Slime Piece quest in Sailor Piece is a quick exploration challenge that sends players across multiple islands. While none of the pieces are extremely difficult to find, knowing the exact locations saves a lot of time wandering around the map.
Once you know where each piece is hidden, collecting all seven becomes a quick trip across the islands instead of a long search.
