The long-awaited Halloween event has finally dropped in Grand Piece Online, and it’s one of the most nostalgic — and chaotic — updates yet. Old bosses are back, new ones have arrived, and a ton of Halloween-themed features have returned to the seas. If you missed out on the past Halloween events, this is your best chance to experience everything again.
This guide covers every new boss, island, item, and event activity you can find during the Halloween 2025 event.
GPO Halloween 2025 Update Guide
1. Returning Halloween Islands
Spooksville Island
Spooksville makes a triumphant return this year. This island remains your go-to spot for Trick-or-Treating, event vendors, and limited-time Halloween cosmetics.
Once you arrive, you’ll notice all the classic Halloween structures have been brought back — glowing houses, eerie lighting, and, of course, the vendor stalls that sell everything from Race Rerolls to Custom Spirit Colors.
Items sold in Spooksville include:
- SP Essence
- Devil Fruit Removers
- Race Rerolls
- Custom Spirit Colors
- Lanterns and Train Signs
- Mummy Wrapping Outfit
- Fruit Bags and Rare Fruit Chests
Just like previous years, this is where you’ll be doing most of your Halloween shopping. However, your Pumpkin Bag has been reset, meaning you’ll need to buy a new one to start trick-or-treating again.
Note: You can earn certain rare drops like the Nightfall Half Shroud through Trick-or-Treating, but it’s extremely rare. Players have reported spending dozens of hours grinding it, so prepare for a long haul if you want one.
2. Trick-or-Treating Returns
Trick-or-Treating works exactly as it did in previous events.
You’ll go around Spooksville visiting doorsteps to collect event currency and occasionally rare items. This activity can drop limited accessories, fruit bags, and components used for crafting or trading.
Notable Trick-or-Treat Drop:
- Nightfall Half Shroud — can also be traded among players
- Pumpkin Bag (2025) — mandatory to start the event
It’s a straightforward event, but it’s the main way to collect Halloween-exclusive items passively while you explore.
3. Transylvania Island & Resurrected Ball Boss
After visiting Spooksville, head to Transylvania Island, the second major Halloween area.
This area hosts one of the most iconic Halloween bosses in GPO: Resurrected Ball, also known as the Head of Ball.
How to Access
You can travel to Transylvania directly from Spooksville — the two islands are close to each other. Once there, set your spawn point near the boss arena so you can easily reattempt the fight.
Boss Details
Name: Resurrected Ball (Head of Ball)
HP: ~60,000
Difficulty: Moderate
Guards: Ball Guards (sometimes absent in this version)
Recommended Strategy:
- Bring a coordinated group to deal with his high HP pool.
- Use high-damage AoE ultimates to burn through his health quickly.
- Soloing is possible, but server hopping helps for efficient farming.
The fight remains similar to previous years, featuring massive attacks and swarming adds that make the area chaotic. Players are reporting that his Ball Guards may sometimes not spawn, which makes the encounter a bit easier than before.
Despite being a returning boss, the fight remains one of the most fun in the entire Halloween event.
4. NEW Boss – Ghost Princess Perona
A brand-new boss joins the Halloween lineup this year — Perona, the Ghost Princess.
She’s located in Second Sea, and finding her may take a bit of exploration, but it’s worth it. Perona’s boss fight introduces unique ghost mechanics inspired by her horror fruit abilities.
Boss Overview
- Location: Second Sea (Ghost Island Area)
- Main Attack: Horror-based ghost attacks
- Weapon Drop: Perona’s Ghost Weapon (new item)
- Difficulty: Easy to Medium
Perona’s attacks can stun and disorient players, so movement and dodging are key.
When defeated, she can drop her exclusive weapon, which is expected to become one of the more sought-after Halloween drops this season.
The Ghost Princess boss is designed to be farmable — solo players can defeat her fairly easily once they learn her movement pattern.
5. The Traveling Merchant & Tailor NPC
Alongside the main event bosses, GPO has added two functional NPCs to spice up customization and trading.
Traveling Merchant
- Appears randomly across the seas.
- Sells valuable items, including Halloween cosmetics and rare resources.
- Inventory rotates, so check regularly.
Tailor NPC
- Lets you customize outfit colors, especially Halloween-themed costumes.
- Perfect for creating a unique look if you’re participating in community events or roleplay.
6. New Battle Royale Map
The Halloween update also introduces a new BR map.
Although details are still limited, the map reportedly features darker aesthetics, seasonal decorations, and spooky fog effects to fit the event’s atmosphere. It’s a fun twist for PvP players looking to test their skills while enjoying the Halloween theme.
7. Tips for Grinding the Event Efficiently
If you plan to farm all bosses and drops, here’s how to maximize your time:
- Set spawn points on each island to save travel time.
- Server hop Transylvania to repeatedly farm the Resurrected Ball boss.
- Keep Trick-or-Treating while waiting for boss spawns for passive loot.
- Buy Race Rerolls and Custom Colors early, as they tend to sell out or become expensive later in the event.
- Use private servers if possible — it’s easier to fight bosses without interference.
8. Active Halloween 2025 Codes
Here are all currently known Halloween event codes:

Longtime players will appreciate the return of Spooksville and Transylvania, while newcomers get fresh experiences with Perona and the merchant systems.

If you’re planning to dive into the event, do it soon. Once Halloween season ends, these bosses and items will disappear again until next year.
