Steal an Egg New Update 10 at a Glance

Abandoned Manor: How to Unlock Access

The Abandoned Manor is open, but getting inside requires more than reaching its gates. The Halloween Dimension expansion links manor access to a mysterious character and a recovery task in the new secret fishing area.

The announced progression is:

1. Explore Forgotten Town and discover its hidden underground fishing area.
2. Meet the mysterious character who has lost something important.
3. Help him recover what he has lost to gain access to the manor.
4. Explore the Abandoned Manor and search for its secrets, including a hidden fusion machine.

The Abandoned Manor Fuse Altar walkthrough supplies the access route: take the train to the town labeled Lost Town in the image, enter the glowing lake, fish up the Manor Key in the secret fishing location, and use it to unlock the mansion.

If you are still working through the earlier Halloween quests, see the Echo the Ghost Dog guide and Phantom Express Ticket walkthrough. Those guides cover the earlier questline; the Update 10 announcement does not say they are prerequisites for manor access.

For the detailed route from the train to the glowing lake and the cave exit to the manor gate, see How to Get Manor Key in Steal an Egg.

Pumpkin Brute and Pumpkin King: Two-Phase Boss Fight

Halloween Part 2 adds an encounter featuring Pumpkin Brute and Pumpkin King. Work together with other players to battle through powerful attacks and defeat the Pumpkin King across an epic two-phase boss fight.

65 Reward Tiers and Six New Halloween Pets

The boss content includes 65 reward tiers, featuring six new Halloween pets and exclusive rewards. There is also a chance to obtain Divine Pumpkin King.

The announcement does not list every tier reward, the six pet names, or the Divine Pumpkin King drop rate. It also does not state that reaching tier 65 guarantees the Divine reward.

For the previously documented collection, browse the Halloween eggs and pets list. That guide lists the original 18 Halloween pets; the six pets announced for Part 2 are additional content. Visit the Steal an Egg Events guide for other documented activities.

Secret Underground Fishing Area in Forgotten Town

Strange things are happening near Forgotten Town. A secret underground fishing area is hidden somewhere in the town, and finding it leads to the mysterious character who needs your help.

The announcement introduces a recovery task here. The illustrated manor walkthrough shows how to enter the fishing location through the glowing lake and fish up the Manor Key used to unlock the mansion.

The earlier Phantom Express location guide shows where to find the train used for the route to town.

Secret Divine Fusion: How to Get Cursed Monarch

A mysterious fusion machine inside the Abandoned Manor unlocks the new Divine Cursed Monarch. You need to work with another player and bring two of each required pet, as shown in the manor walkthrough:

Need the fishing ingredient? Follow How to Get Ghost Fish in Steal an Egg: obtain a rod, fish in any body of water on the map, and complete the minigame triggered when a fish pulls you into the water.

Unlock the manor, locate the machine, and coordinate with another player to bring the required pets. The altar is at the top of the staircase. Both players must each have both pets: one Eternal Ghost Fish and one Divine Voidseer Pumpkin. The Ghost Fish fishing percentage has not been disclosed. Divine Voidseer Pumpkin is obtained during global spawn, similar to other Divine spawns. Follow the Abandoned Manor Fuse Altar guide for the complete route and ingredient quantities.

For background on an earlier cooperative fusion system, read How to Get Fused Pets in Steal an Egg. That guide covers the Secret Shrine's recipes; use the manor machine's own prompts for Cursed Monarch.
