Key Brainrots & How to Get Them
Las Sis — Craftable Secret
Las Sis is listed as a secret Brainrot obtainable through the game’s craft machine. That means collecting the recipe components and crafting during an event window is the most reliable path.
La Extinct Grande — Limited “Grande” Variant
La Extinct Grande is the bone-themed La Grande variant. Wiki pages and community reports say it requires owning three Extinct-type Brainrots (Extinct Ballerina, Extinct Tralalero and Extinct Matteo) to spawn. It was released as a limited-stock Secret and has seen stock adjustments reported by the community.
67 — New Secret Brainrot
The secret Brainrot named 67 was added in the Extinct update (community records place its addition on Sept 13, 2025). Unlocks are shown in recent video walkthroughs; expect tightly-timed conditions during event windows.
Step-by-step Strategy
- Watch the event visual cues and timer — be ready when the map indicators change.
- Collect craft components early if you want Las Sis (craftable), so you can craft instantly during the event.
- Secure Extinct Ballerina, Extinct Tralalero, and Extinct Matteo — these are required to spawn La Extinct Grande.
- Use private servers or coordinated groups to control rituals/spawns and reduce interference.
- Follow up-to-date video guides for exact button presses / positions — the community often posts the most current step-by-step runs.

- Have craft components gathered (Las Sis) ✅
- Have funds & small trade backup ✅
- Coordinate with 1–3 friends (private server recommended) ✅
