Creatures of Sonaria Survive Kaiju Animals event
Creatures of Sonaria Antler Spirit: Start Time, Countdown & Rewards

Creatures of Sonaria is set to unlock a new creature, the Antler Spirit, in a limited event running from August 28 to August 31, 2026. The developer, Sonar Studios, describes it as a creature with a scorched side that hints at “a dangerous past,” and pairs its debut with the return of a long-awaited subspecies of an earlier creature. Both are tied to the same short window, so this is a get-it-now unlock rather than a permanent addition.
The survival sim remains one of Roblox’s busier creature builders, with about about 40,000 players in-game and a lifetime audience past two billion visits. Well over half a million players have already flagged the Antler Spirit event as interesting ahead of its start, so the opening hours are likely to fill servers quickly.

What’s in the Antler Spirit event
The headline draw is the Antler Spirit itself, a brand-new creature to unlock during the run. Alongside it, the developer’s listing promises a second arrival for the same week:
- The Antler Spirit creature — a new unlockable whose scorched design is meant to nod to a darker chapter in the game’s lore.
- A returning subspecies — a long-awaited variant of a past creature, added the same week as a bonus.
Both are unlocked by playing during the event window; once it closes, this particular pairing is no longer on offer.
When it runs and how to plan
The event opens on August 28, 2026 at 4:20 PM ET and closes on August 31, 2026 at 4:30 PM ET — a window of roughly three days. The page also lays that window out across the major world time zones, so readers outside North America can see exactly when it starts and ends without doing the math; the exact window and countdown are on the card above. As of August 23, the event is still ahead of its start date.
Three days is a tight window compared with the game’s longer seasonal runs, and there is no partial credit for showing up late. If you want the Antler Spirit and the returning subspecies, treat the first day or two as the safe bet rather than leaving it to the final afternoon.
How it fits the game’s rhythm
Sonar Studios keeps these limited creature drops on a near-weekly beat. Return of the Claw (August 21–24) and Ancient Species Awaken (August 21–28) are both scheduled just before this one, with Ancient Species Awaken’s close overlapping the Antler Spirit event’s opening by about ten minutes — barely any gap between the two. That cadence echoes last year’s Land Sea Sky series, which stepped through weekly “weeks” of content. The practical takeaway: if you miss a creature here, the next event is rarely far behind, but each unlock is locked to its own window, so a skipped one is a skipped one.
