Steal An Egg Halloween Dimension — Biomes, Pets & Phantom Express

Update 9 shipped on 2026-10-17 and opened the first half of what the developers billed as a “massive two-part Halloween event” — teased on 2026-10-11, live six days later. Everything below comes from the official announcement in the Steal An Egg Discord; where the team has not published a detail, this guide says so rather than guessing.

How to enter the Halloween Dimension

  • Enter the spooky portal at spawn. The announcement describes access through that portal and does not mention a Speed requirement, unlike the regular speed-gated biomes.
  • The dimension contains 3 new biomes: Graveyard, Haunted Swamp and Abandoned Manor.
  • Each biome holds 6 new pets — 18 new pets in total. The announcement does not list their names or rarities, so they are not listed individually on the pets page yet.
  • The dimension also hides secrets and special events, including the Blood Moon and the Pumpkin Collection Event.

Echo the Ghost Dog

  • Echo has lost his memories and needs help to get them back.
  • Find his missing memories and reunite him with his owner.
  • His owner may have a special reward waiting for you.
  • The announcement does not say where the memories are hidden. Treat any location you see on social media as unverified until it is confirmed officially.

Phantom Express and the Spectral Mutation

  • Find the mysterious Phantom Express Ticket to unlock access to the train.
  • Every 30 minutes — on the hour and on the half-hour — the Phantom Express arrives.
  • Board the haunted train and ride it to a mysterious new area.
  • That new area unlocks the Spectral Mutation.
  • Neither the ticket’s spawn rules nor the Spectral Mutation multiplier have been published. The documented mutation layers are on the mutations page.

The two new eggs

Halloween Egg (store)

  • A brand-new Halloween Egg is available in the store.
  • It carries a rare chance to reroll your hatch into the Zombified Re-Roll.
  • Price and odds are not published.

Candy Corn event egg

  • Collect Candy Corn by returning eggs and defeating monsters.
  • Visit the giant pumpkin at the Halloween spawn to exchange Candy Corn for exclusive event eggs.
  • Candy Corn prices and the hatch pool are not published either.

Part 2 — the “New Expansion” (live 2026-10-24)

  • The Halloween event was announced as two parts; part one is the Halloween Dimension described above.
  • Part 2 went live on Saturday, 2026-10-24. The official Roblox event listing scheduled it for 15:00 UTC — one hour after the Part 1 listing closed — and subtitled it “New Expansion”.
  • The listing teases a sealed portal beyond the Abandoned Manor gates and asks “who opened the Halloween Dimension and why” — a story reveal.
  • The listing names no bosses, eggs, pets, rewards or entry costs. Detailed Part 2 content had not been published in the official channels reachable when this guide was updated, so nothing beyond the listing is claimed here.
  • The update log records the details as soon as they drop.
