How to Find All Slime Pieces in Sailor Piece (June 2026)

Looking for all the Slime Pieces scattered across Sailor Piece? You have come to the right place. Collecting all 7 Slime Pieces unlocks the ability to craft Slime Keys, which you need to spawn the powerful Rimuru boss. In this guide, I will walk you through every single Slime Piece location so you can complete the Slime Collection quest and unlock that crafting option.

This quest is one of the more involved collection tasks in Sailor Piece, but with clear directions and visual landmarks, you will have all pieces gathered in no time. Let me show you exactly where to go.

Slime Collection Quest Overview

Before hunting for Slime Pieces, you need to start the quest properly. Head to Slime Island and find the Slime Key Crafter NPC. This character gives you the Slime Collection quest and explains what you are looking for.

Once you accept the quest, your goal is simple: find all 7 Slime Pieces hidden across different islands. The game will notify you when you collect each piece, and when you grab the final one, you will see a message confirming your Slime Quest is completed and the craft is now unlocked.

Here is what makes this quest straightforward: your progress saves automatically. If you leave the game after collecting three pieces, those three stay collected when you return. You can also collect pieces in any order that works for you.

How to Find All Slime Pieces in Sailor Piece

Here are all 7 Slime Piece locations with step-by-step directions. I have listed them with clear landmarks so you can spot each one easily.

Slime Piece 1: Desert Island

Travel to Desert Island through the portal. From your spawn point, walk forward and look for the massive dragon fossil skeleton on the ground. The Slime Piece sits right next to this fossil. You cannot miss it once you spot the bones. Just walk up and interact with the glowing piece to collect it.

Slime Piece 2: Snow Island

This one tricks a lot of players. Port to Snow Island and head toward the cluster of small shacks near the spawn area. Jump onto the roofs of these shacks and look for a tree behind them. The Slime Piece is tucked behind that tree. You will need to use your jump and dash abilities to reach it properly.

Slime Piece 3: Starter Island

Return to Starter Island where you first began the game. Look for the large tree with extended branches near the center of the island. Climb up onto one of the main branches. The Slime Piece rests on this branch, waiting for you to grab it. This is one of the easier pieces to spot once you know where to look.

Slime Piece 4: Jungle Island

Make your way to Jungle Island. From the spawn point, scan the area for a wooden watchtower structure. The Slime Piece is located at or near this watchtower. Walk around the base first, then check the upper platform if you do not see it immediately. The jungle foliage can obscure your view, so take your time looking.

Slime Piece 5: Shibuya Station Island

This location requires some running. Spawn at Shibuya Station Island and locate the tall skyscraper on your right side. Walk straight from spawn and go behind this building. Be careful here because the Yuji boss patrols this area. Run past the boss to the far end behind the skyscraper where the Slime Piece waits in a corner many players overlook.

Slime Piece 6: Hueco Mundo

Portal to Hueco Mundo and look for a domed building in the area. Near this structure, you will find black panels on the ground or walls. The Slime Piece is hidden among these black panels. Check around the perimeter of the domed building thoroughly. The dark color scheme of this island makes the piece blend in, so look carefully.

Slime Piece 7: Shinjuku Island

Your final piece is on Shinjuku Island. From spawn, search for a withered or dead tree. This tree stands out because it looks different from the healthy vegetation around it. The Slime Piece rests at or near this withered tree. Once you collect this seventh piece, you will receive the completion notification.

How to Craft Slime Keys

Now that you have all 7 Slime Pieces, you can craft Slime Keys. But you need one more ingredient: Slime Shards.

Slime Shards drop from Slime Warrior enemies. These mobs are Level 8000, so come prepared if your character is not strong enough yet. The drop rate is not guaranteed, so expect to farm them for a while. Defeating Slime Warriors repeatedly is the fastest way to build up your Shard supply.

Here is the crafting formula: 2 Slime Shards create 1 Slime Key. Return to the Slime Key Crafter NPC on Slime Island to perform the crafting. You can make as many keys as you want, provided you have enough Shards.

So what do Slime Keys actually do? They are required to spawn the Rimuru boss. This boss fight is a major challenge in Sailor Piece, and you cannot access it without a Slime Key in your inventory. Think of the entire Slime Collection quest as a prerequisite for this high-level content.

The Rimuru boss also drops Slime Shards as loot, which creates a nice farming loop if you plan to craft multiple keys.

Ready to Hunt Slime Pieces

That covers everything you need to know about how to find all Slime Pieces in Sailor Piece. Start at Slime Island with the Slime Key Crafter NPC, visit each of the 7 islands, collect the pieces using the landmarks I described, and you will have your Slime Key crafting unlocked in no time.

Remember to farm Slime Shards from Level 8000 Slime Warriors once you finish the collection. Two Shards give you one key, and that key opens the door to the Rimuru boss fight. Good luck out there.
