The Extinct Event Update was released on September 13, 2025, for the Roblox game Steal a Brainrot. This update introduced a variety of new content, including a limited-time event, new brainrots, traits, and a ritual. Unlike the typical weekly updates, this one brought fresh mechanics and activities, providing players with engaging new challenges. The update also coincided with the game achieving a record-breaking 24 million concurrent users (CCU), surpassing previous highs set by games like Grow a Garden. Additionally, a bug fix addressed the “snap issue,” where the Sammy character’s snap animation previously triggered a cutscene that caused players to lose brainrots from the conveyor belt. Now, the snap can be viewed from anywhere in the base without interruptions.
Extinct Event
During the Extinct Event, the map transforms into a dry, arid landscape with bones protruding from the ground and walls, creating a thematic desert-like environment. The event occurs every 2 hours on each server, with a timer visible above the Archaeologist NPC at the center of the map for tracking the next occurrence.
One of three Extinct Brainrots (Extinct Ballerina Cappuccina, Extinct Matteo, or Extinct Tralalero) spawns randomly on the conveyor belt during the event. Players must purchase these with in-game cash, and due to high competition on public servers, it’s recommended to play on private servers or coordinate with friends. Collecting all three Extinct Brainrots allows players to redeem La Extinct Grande from the Extinct Event NPC. This reward is limited to 500,000 units total, making it a race to be among the first to complete the set. Players can trade Extinct Brainrots via the official Discord to speed up collection without waiting for the next event cycle.
New Traits
Two new traits were added in this update:
- Skull Trait: Provides a 4x multiplier. When equipped, a ribcage appears on the chest of brainrots passing the conveyor belt structure.
- Graffiti Trait: Provides a 6x multiplier. Leaves colorful graffiti on the ground. Obtained via the Chicleteira Ritual (see below).
New Ritual
The Chicleteira Bicicleteira Ritual (also referred to as the Chicleteira Ritual) is a new player-initiated event. It requires two players, each owning a Chicleteira Bicicleteira brainrot in their base (stolen ones do not work).
Steps:
- Both players go to the start of the conveyor belt (at the red carpet area) and stand next to it, facing the direction where brainrots emerge.
- Position correctly to “connect” the brainrots, triggering the ritual and spawning a town-like structure as confirmation.
- This causes Los Chicleteiras to spawn.
After spawning, Chicleteira Bicicleteira figures holding spray paint appear on both sides of the conveyor belt. They randomly spray paint passing brainrots, granting a chance to obtain the Graffiti Trait. Los Chicleteiras itself has a base income of $7M/second and can mutate for higher values (e.g., up to $10M/second or more).
