Steal an Egg Update 10, titled Halloween Part 2, launched on October 24, 2026. This update introduces a new exploration area, the Abandoned Manor, a two-phase Halloween boss fight, and a new Boss Mastery system with 65 reward tiers.
Whether you want to collect the new rewards or unlock Cursed Monarch, a Divine pet, there are plenty of goals to work toward. However, entering the manor requires a specific key, and finding it means taking the Phantom Express to a hidden fishing area.
This guide explains how to get the Manor Key, where to find the new fishing area, how the Halloween boss fight works, and what you need to fuse Cursed Monarch.
How to Unlock the Manor Door
Quick Answer: Take the Phantom Express to Forgotten Town → Enter the green whirlpool → Fish near Gus → Get the Manor Key → Unlock the manor door.
How to Get the Manor Key
The Manor Key can be obtained by fishing in the underground area accessed through the green whirlpool in Forgotten Town. You cannot obtain it by fishing in just any body of water.
Before starting, make sure you have unlocked access to the Phantom Express and obtained the Haunted Rod.
Step 1: Complete Echo's Quest
First, head to the Halloween Dimension and find Echo, the ghost dog NPC. Echo is located near the graveyard, beside the house with a witch-hat-shaped roof.
Echo needs your help finding four missing items:
- A collar
- A chewed bone
- A favorite toy
- A photo of Echo's owner
Search the Halloween area for these items and return them to Echo. Completing this quest unlocks the next part of the route, involving the Ghost Fisherman and the Phantom Express.
Step 2: Get the Phantom Express Ticket and Board the Train
After completing Echo's quest, head to the Ghost Fisherman area.
Obtain the Haunted Rod and complete the underwater obstacle challenge. Reach the chest at the end of the course to collect the Phantom Express Ticket.
Next, head to the Phantom Express station in the Halloween Dimension and wait for the train to arrive. The train runs every 30 minutes, at :00 and :30. Check the in-game countdown for the next departure, then board the train to travel to Forgotten Town.
Step 3: Enter the Green Whirlpool
After arriving in Forgotten Town, find the lake and look for the glowing green whirlpool in the water.
Enter the whirlpool to reach the hidden underground fishing area. Equip the Haunted Rod and fish in the designated area near Gus, the fisherman NPC.
Keep fishing until the Manor Key appears in your inventory. You can also catch other rewards, including Candy Corn, while fishing.
Step 4: Unlock the Abandoned Manor
After obtaining the Manor Key, return to the Abandoned Manor and approach the chained door.
Interact with the door to unlock it and enter the manor, where you can find the fusion altar.
Once inside the manor, head upstairs to the room with books, purple lighting, and four pedestals. This is where you can fuse Cursed Monarch.
The required materials are:
| Pet | Rarity | Quantity |
|---|---|---|
| Ghost Fish | Eternal | 2 |
| Voidseer Pumpkin | Divine | 2 |
Ghost Fish can be obtained through Halloween fishing with the Haunted Rod. Voidseer Pumpkin is from Abandoned Manor Halloween egg.
The fusion produces a Cursed Monarch Egg, which you can hatch to obtain Cursed Monarch. Work with another player to prepare the required pets and complete the fusion at the altar.
Is the Abandoned Manor Worth Exploring?
The Abandoned Manor is one of the most visually striking additions in the second phase of the Halloween update. Unlocking the door allows players to enter the interior and use the special fusion altar, giving collectors another goal to work toward.
However, if you expect a large area packed with activities, the Abandoned Manor may feel a little underwhelming. Beyond its role in the fusion system, there is not much else to explore.

Along with the new exploration area, Steal an Egg Update 10 introduces a new boss fight and its associated rewards. Each successful Pumpkin King boss victory grants one Boss Mastery point.
The boss encounter has two phases: Pumpkin Brute and Pumpkin King. You must defeat both phases to complete the encounter and earn the Mastery point.
During the second phase of the fight, Pumpkin King throws bombs, so keep moving and avoid dangerous areas. Clear the vines blocking the cannons and use the cannons to attack the boss.
The currently available reward milestones are listed below:
| Total Boss Victories | Reward | Rarity |
|---|---|---|
| 3 | Bubblelord | Epic |
| 10 | Coffin Crawler | Legendary |
| 17 | Bell Scream | Mythic |
| 30 | Phantom Banshee | Cosmic |
| 45 | Vespera | Secret |
| 52 | Pumpkin Scythe | Weapon |
| 65 | Pumpkin Brute | Eternal |
Among these rewards, Pumpkin Scythe is a particularly notable prize. If you want a reward with both seasonal appeal and practical value, it may be one of the most attractive items to aim for.
Defeating Pumpkin King 65 times unlocks one Eternal Pumpkin Brute through Boss Mastery. Divine Pumpkin King is a separate random drop.
