The Extinct Event begins immediately when the update launches on September 13, 2025, at 12:00 PM PT. The event runs until September 19, 2025, giving players approximately one week to collect all Extinct Brainrots.
Extinct Brainrots spawn every 2 hours during the event period. Only one of the three Extinct Brainrots (Extinct Ballerina, Extinct Matteo, or Extinct Tralalero) will appear on the conveyor belt at each spawn interval.
If you miss a spawn, you'll need to wait for the next 2-hour interval. Each spawn is random, so there's no guarantee which Extinct Brainrot will appear next. Persistence and regular checking are key to collecting all three.
Yes, the La Extinct Grande is available in strictly limited quantities. Only players who collect all three Extinct Brainrots first will receive this reward, making it one of the rarest Brainrots in the game.
The ritual mechanics suggest you can perform the Chicleteira Ritual as many times as you have the required sacrifice materials (2 Chicleteira Bicicleteira per ritual).
Based on previous limited-time events, Extinct Brainrots will likely become unobtainable after the event concludes, making them permanently rare collection items.
While the core event mechanics don't require Robux, having sufficient in-game currency (Cash) is essential for purchasing the Extinct Brainrots when they spawn.
