What the official announcement says
The event copy describes a mysterious structure that acts as a gateway to the Halloween Dimension, monster roars, powerful bosses and secret eggs, and calls it a massive two-part Halloween event. It is an announcement, not patch notes: it does not list mechanics, stats or rewards.
Preparation checklist
- Note the start: Oct 17, 15:00 UTC (11:00 AM ET / 8:00 AM PT). Joining about 15 minutes early is a congestion tip, not guaranteed access.
- Do not pre-spend on guessed boss requirements, egg prices or Robux packs that are not shown in your live server.
- Free base / inventory space in case new eggs or pets appear.
- After start, read in-game prompts and the Events panel before trusting community lists.
Relation to Mounts and Admin Abuse
The Mounts (Update 8) listing ended Oct 11, 2026, 19:00 UTC, before this event’s Oct 17 start. Community guides describe a Saturday ~15:00 UTC Admin Abuse pattern; Oct 17 is a Saturday, but the official Halloween Dimension record does not mention Admin Abuse, so treat any overlap as unconfirmed.

The status line at the top of this page updates from your device clock against the official window. Always confirm in your live server.
What are the secret eggs and bosses?
Not verified yet. The official copy only names them. We will add details once there is in-game evidence or official patch notes.
Does Mounts end before Halloween starts?
Yes, by listing times: Mounts ended Oct 11, 19:00 UTC; Halloween Dimension starts Oct 17, 15:00 UTC. A listing end does not by itself prove when features leave servers.
