Steal a Brainrot Mutations — All 15 Multipliers
Mutation is the multiplier that travels with the brainrot, so it is what people are really trading when they trade a "clean" versus a "mutated" copy of the same thing. Collecting enough of one mutation also unlocks a matching base skin — see index completion for the thresholds.

How much a mutation is actually worth
Income is base × (mutation + traits). With no traits, a Crystal brainrot earns
exactly 13 times what a plain one earns; a Gold one earns 1.25 times. That gap is
larger than most rarity jumps, which is the reason a mutated Mythic can out-earn a plain Brainrot God. Put your own numbers into the income calculator to check a trade before you accept it.
Which mutations can you still get?
Gold, Diamond and Rainbow spawn on the red carpet year-round — Gold on roughly one in ten spawns. Everything else is tied to a seasonal window: Candy, Lava, Galaxy, Yin Yang, Radioactive, Cursed, Divine, Cyber and the newest additions each had their own event period. When an event ends the mutation stops appearing, but existing copies keep their multiplier, which is why off-season mutated brainrots hold their value in trades.
