Inside Brainrot Head Brainrot Trader
Last updated: June 2026
What Is the Brainrot Trader?
The Brainrot Trader is an NPC shop in the lobby where you sell Brainrots you no longer need. Selling converts units into instant cash — useful for funding Coil purchases, head unlocks, or rebirth savings.
When to Sell vs Keep
Sell: duplicate C-tier fillers, units replaced by strict upgrades, excess commons after base is full of B-tier or better.
Keep: rebirth-required units (even if temporarily useless), S-tier anchors, units needed for index completion — Index Guide.
Trader Strategy
Before rebirth, verify which Brainrots the Rebirth UI consumed on previous tiers — never sell a required unit before registering it. After rebirth, sell low tiers aggressively to fund recovery.
