Creatures of Sonaria: LEGO NINJAGO End Time, Countdown
Creatures of Sonaria is in the middle of a packed run of weekly events, and the headline right now is a returning LEGO crossover. The LEGO NINJAGO collaboration built around the Arc Dragon of Life is live through Friday, August 28, 2026, and it arrives bundled with a full redesign of one of the game’s crab creatures. Two more creature events follow on back-to-back Fridays after it. This page lays out each confirmed event — what it is, when it starts, and when it ends.
By the numbers, this is one of Roblox’s largest survival experiences. Sonar Studios’ creature world has logged about 2,200,000,000 visits and sits at about 11,000,000 favorites, with about about 36,000 players in the game right now.

Current and upcoming events
The schedule has settled into a steady weekly rhythm — each new event has opened on a Friday afternoon, right around 4:20 PM ET. Exact start and end times for every event are in the schedule above.
LEGO NINJAGO: Arc Dragon of Life
The marquee event is Creatures of Sonaria’s latest team-up with the LEGO Group, a LEGO NINJAGO crossover centered on the Arc Dragon of Life. It has been live since Friday, August 21 and runs through Friday, August 28, 2026, closing at 4:30 PM ET — the longest window of the current batch at a full week (that end time is 1:30 PM PT and 8:30 PM UTC), with about 2 days left still to go. In the developer’s setup, the Arc Dragon of Life turns up weakened, and players work to restore it to full strength before taking on an evil that has spread across the land; clearing the event unlocks a new creature at no cost while it is live. The same event also folds in a long-awaited redesign of one of the game’s ancient crab creatures, along with a new subspecies of it. Interest is heavy, with about 660,000 players planning to join.
Antler Spirit
Next up is the Antler Spirit, a new creature that Sonar Studios says carries burn marks from some past ordeal. It runs from Friday, August 28 at 4:20 PM ET through Monday, August 31, closing at 4:30 PM ET, a shorter weekend window than the LEGO event. The same week also adds a long-awaited subspecies of an earlier creature. Interest is strong, at about 600,000 players so far.
Rock-Jaw Monster
The following Friday brings the Rock-Jaw Monster, which Sonar Studios calls a hard-hitting creature built for smashing through rock. It opens Friday, September 4 at 4:20 PM ET and runs through Monday, September 7 at 4:20 PM ET — another three-day weekend event. It is currently drawing the largest interest of the three, with about 690,000 players planning to unlock it.
Each of these creatures is tied to its event window — once an event wraps, its reward leaves the rotation, so every unlock is available for a fixed stretch rather than permanently.
