Steal a Brainrot mutations & traits explained

The short version

Every brainrot has a base value, and two things can multiply it: a mutation and traits. The key difference is how many you can have. A brainrot carries at most one mutation, but it can stack several traits at once. Both make a brainrot worth more, so they're the first thing to check before any trade.

Mutations — pick one

A mutation changes how a brainrot looks and multiplies its value and income. A brainrot can only ever have one mutation at a time — they don't stack, so a Gold brainrot can't also be Rainbow.

• Gold and Diamond — the common, smaller multipliers you'll see most often.
• Bloodrot and Candy — mid-tier mutations, often from events.
• Galaxy, Rainbow and Phantom — the top end; these multiply value the most.
• Higher mutation = a much bigger multiplier, so the same brainrot can be worth a little or a lot depending on which one it has.

Traits — these stack

Traits are permanent boosters that come from events and limited drops. Unlike mutations, a brainrot can carry several traits at once, and they add up — so a brainrot with two or three strong traits is worth far more than a plain one.

• Strawberry and Meowl — among the strongest traits, big multipliers on their own.
• John Pork, Skibidi and other event traits — solid boosters you'll see stacked together.
• Each extra trait adds more on top, so stacked traits can multiply value several times over.
• Traits are tied to events, so older ones get harder to find and tend to climb in demand.

How they combine

Start with the brainrot's base value, apply its one mutation, then add any traits on top. A high-rarity brainrot with a top mutation and a couple of strong traits is where the biggest values come from — far above the same brainrot with nothing on it.

• Base value comes from rarity — Common up through Brainrot God, Secret, OG and Admin.
• The one mutation multiplies that base.
• Stacked traits multiply it further.
• So 'which brainrot' is only half the story — the mutation and traits decide the rest.

Values are reference points, not prices

The numbers you see here are roughly what the community agrees a brainrot is worth in trades — a sanity-check to keep swaps fair, not a real-money price and not an official figure. Multipliers and trait drops shift over time, so always check a current value rather than going by name alone. A trade is only really fair when both players are happy with it.

What to check before you trade

Trading is item-for-item and in-game — swap brainrots (and Seasonal Base Skins) right in the trade window that opens from the in-game trade button. Both sides add what they agreed and both confirm before it goes through.

• Confirm the exact mutation — there's only one, and it changes the value hugely.
• Count the traits and check each one is really there, not just claimed in chat.
• Match the Roblox @username to the person you arranged with — display names get copied.
• Re-check the trade window right before you confirm, and never hand items over first.
• Run both sides through the free Win / Fair / Lose calculator so you know it's roughly even.
