Observatory - Blox Fruits (Unbound Werewolf)

The Observatory is a dimension where the Unbound Werewolf resides. It doesn't appear on its own: you need to spawn it via the Trick or Treat doors, a content linked to a game event.

How to get it

Do Trick or Treat at the doors near the Mansion (Third Sea), the Café, or Middle Town: the portal is hidden in one of them. The event icon near the compass gives you the exact location. When the message "The beast awakens to hunt for prey" appears, activate the first door leading to the structure.

What you'll find there

Unbound Werewolf: the boss that resides in this dimension

Good to know

The on-screen message "The beast awakens to hunt for prey" confirms that the Observatory has appeared.
Use the event icon near the compass to locate the right door instead of searching randomly.
